Green chemistry requires concepts and industrial ecology using natural systems to rid industrial water flow from heavy metals, which effects badly on health and environment. For this purpose, the changes in coefficient of distribution of mercury has been studied in system with two phases, liquid (water contaminated with mercury) - solid (metal pyrite) correlation of the following factors: Time of mixing phases, size of the developed steel, change the values of pH, concentration of elemental mercury, the concentration of calcium as a competitor to the occupation of sites available on the solid phase, the ratio V / M presents the water phase size on the mass of phase, which reflects the remaining time of water phase in the solid phase. The results show that pyrite can be proposed as safe environmental solution for purification of water phase of mercury, after controlling for some operation transactions.

Critical review
تقدم الدراسة مساهمة علمية هامة في مجال تنقية المياه الصناعية باستخدام مواد طبيعية مثل البيريت، وهو ما يتماشى مع مفاهيم الكيمياء الخضراء. ومع ذلك، يمكن توجيه بعض النقد البناء للدراسة. أولاً، لم تتناول الدراسة بشكل كافٍ تأثير العوامل البيئية الأخرى مثل درجة الحرارة والملوثات الأخرى التي قد تكون موجودة في المياه الصناعية. ثانياً، على الرغم من أن النتائج مشجعة، إلا أن الدراسة لم تقدم تحليلًا اقتصاديًا شاملاً لتكلفة استخدام البيريت مقارنة بالطرق التقليدية الأخرى. أخيرًا، كان من الممكن أن تكون الدراسة أكثر شمولية إذا تضمنت تجارب ميدانية بالإضافة إلى التجارب المخبرية لتقييم فعالية البيريت في ظروف واقعية.

The changes in coefficient of distribution of lead and cupper has been studied in system with two phases, liquid water contaminated with lead and copper-solid (natural Phosphate of Syria) correlation of the following factors: Time of mixing phases, size of the developed steel ,change the values of PH ,concentration of elemental lead and concentration of element capper ,the concentration of calcium as a competitor to the occupation of sites available on the solid phase, the ratio V\m presents the water phase size on the mass of phase ,the Percentage removal of lead from aqueous samples prepared in the laboratory91,57-99,95% were the best conditions for a vast proportion removed can be summarized as follows: PH=[6,63-10,11], Time of mixing phases =60 minutes and V/m=1000. The Percentage removal of copper from aqueous samples prepared in the laboratory 95,27 -99,96 % were the best conditions for a vast proportion removed can be summarized as follows: PH= [7,89-11,01] , Time of mixing phases =60 minutes and V/m=1000. Ideal conditions have been applied that were obtained according to laboratory tests on water samples from industrial input to Banias refinery and water samples from industrial drainage to Syrian company for oil transport after Removal for lead was( 100%,99 %). Removal for copper was( 100%,98 %) .
In this research, the natural pyrite ore found in Tartous Governorate was described by studying the two samples taken from Hosn Suleiman -Safita (A) and Al Qadmous (B) area, in addition to studying the optimum conditions for pyrite dissolution (pH - time - quantity) with aerobic conditions. The results of X-ray diffraction (XRD) showed that the sample (A) is mainly composed of pyrite mineral and does not contain impurities, while sample (B) is composed of pyrite mineral combined with a small amount of calcite mineral, and these results were confirmed by the result of (FTIR) infrared spectroscopy and Polarised light microscopy (PLM(. The iron percentage in the two samples (A,B) is ranged between (42.6 – 43 %) and the sulfur percentage is between (40 – 53.7 %). With regard to pyrite dissolution, the results showed that pyrite taken from Hosn Suleiman (A) begins to dissolve at pH values less than 4.5, and the contact time is about 6 hours. By Comparing the results of sample (A) with sample (B), we found that the dissolution of sample (A) was about three times less than the dissolution of sample (B), and this is due to the fact that sample (A) contains pure and well crystallized pyrite ore while sample (B) contains pyrite combind with calcite, which increases its solubility.
Studied the distribution coefficient of elemental copper and lead contaminants in the aqueous phase using a Bi-phase system: solid phase (the sands of Palmyra) and liquid phase (water containing the former two elements), where they were sampling sand samples from different regions in Palmyra to investigate for possible use as an adsorbent for elemental copper the lead from contaminated water, and after adjustment for certain transactions from time mixing phases, granular size, concentration of hydrogen ions, the concentration of the contaminated ingredient, the concentration of rival element (calcium) in addition to the ratio v / m in order to get the best rate for removal of these elements. The removal rate of copper componentamounted to 99.9% using four sites samples of sand a Palmyra, (al qareaten - the third leg to pump crude oil T3 - Alhl field - the valley between Mount aldahek and Sokhna) For lead removal ratio stood at 76.35% for the qareaten and 87.75% of the station the third to pump crude oil and 95 0.0% of the field Alhl and 96.25% of the valley between Mount aldahek and Sukhna. The application of the conditions that we have obtained in the laboratory to industrial water samples from the water income for the unity of treatment in Banias refinery and Water Company Drinaj of the Syrian Company for Oil Transport and the ratio of the removal of lead in the four samples ranging from ( 97.79 - 100)% for water Banias Refinery Company ranged between (83.89 - 88.08)% for water Syrian Company for Oil Transport, while the percentage of removal of the copper in the four samples ranging from (96.52 - 99.37)% for water Banias refinery Company and ranged ratio remove copper from the Syrian Company for Oil Transport water between (82.66 - 96.28)% in four samples.
This study aims to use the ash formed from the burning of firewood and the different pruning residues to remove the hardness of water Soda ash was characterized using different techniques, including XRD,flame spectroscopy , volume titration and ot hers. These methods aim to determine the composition of the ash and the components which are contributing to the removal process. The optimum mixing time was determined using certain amount of soda ash to the hard water and the water hardness was determined in the rang of time (0.5, 1, 2, 3, 4 and 5h) where the ideal time was 3 hours. The removal ratios were determined when the mixing time of the two phases was 3 h, and adding directly the following quantities of ash (0.5,1,2,3,5,7,10,15,20,25) g to 200 ml of highly hardened water. The removal rate was increased by increasing the amount of added ash. The removal rate was approximately 50% when 1 g of ash was used and the complete removal rate of 100% was achieved when the amount of ash was 25 g.
The study was carried out to remove of heavy metals (V+5, Ni+2) under static conditions from aqueous solutions by Syrian Zeolite mineral extracted from south of Syria. The results revealed that operational conditions such as initial solution pH and concentration, adsorbent particle size, the presence of competing cations, are able to affect the adsorption capacity and efficiency of natural zeolite.
