This search aims to study the adsorption of Cu ions from their solutions on the surface of silicon oxide. These experiments were in five groups, at the first three groups the amount of the adsorbent was constant, and the concentration of the adsorbing ions was changed, after the adsorption is ended the concentration of Cu remaining ions in the solution was measured, then the quantities of the adsorbing ions on the surface of silicon oxide were determined.

Research summary
تهدف هذه الدراسة إلى تقييم كفاءة امتزاز شوارد النحاس من المحاليل المائية باستخدام سطح متعدد حمض السيليكون. يعتبر حمض السيليكون من أهم مكونات القشرة الأرضية والمواد الرسوبية، وهو يستخدم هنا كجسم ماز لشوارد النحاس. تم إجراء التجارب في خمس مجموعات، حيث تم تثبيت كمية الجسم الماز في المجموعات الثلاث الأولى وتغيير تركيز الشوارد الممتزة، بينما في المجموعتين الرابعة والخامسة تم تثبيت تركيز الشوارد الممتزة وتغيير كمية الجسم الماز. أظهرت النتائج أن كفاءة الامتزاز تزداد بزيادة تركيز المحلول أو كمية الجسم الماز، ولكن هذه الزيادة ليست خطية. تم تمثيل النتائج باستخدام معادلات لانغموير وفروديندليش، وأظهرت النتائج توافقًا مع هذه النماذج. تشير النتائج إلى أن الامتزاز يكون فعالًا عند تراكيز منخفضة من شوارد النحاس، مما يعكس إمكانية استخدام هذه الطريقة في معالجة المياه الملوثة بشوارد النحاس.
Critical review
تعتبر هذه الدراسة خطوة مهمة نحو فهم كفاءة امتزاز شوارد النحاس على سطح متعدد حمض السيليكون. ومع ذلك، هناك بعض النقاط التي يمكن تحسينها. أولاً، الدراسة تركز فقط على شوارد النحاس دون النظر إلى تأثير الشوارد الأخرى التي قد تكون موجودة في المياه الطبيعية. ثانياً، لم يتم تناول تأثير العوامل البيئية المختلفة مثل درجة الحرارة ودرجة الحموضة بشكل كافٍ. ثالثاً، النتائج قد تحتوي على نسبة من الخطأ نظراً لاستخدام جهاز الامتصاص الذري، وكان من الممكن تحسين دقة النتائج باستخدام تقنيات تحليلية أكثر تطوراً. على الرغم من هذه النقاط، فإن الدراسة تقدم أساساً جيداً يمكن البناء عليه في الأبحاث المستقبلية.

The Syrian natural zeolite from om'ozon area has been studied as adsorbent for Ni(II) ions from aqueous solution. The removal of Ni(II) ions under different conditions was studied adsorption of Ni(II) enhanced with an increase of initial concentratio n, temperature and PH .all experiments were carried out at contact time 6h. The amount of Ni(II) adsorption was increased from 16.36 mgNi/g for initial solution concentration of 100mg Ni/l to 71.33 mgNi/g (for C0=1000mgNi/L). The experimental data fitted well to Langmuir isotherm. The maximum capacity was qmax=142.85mgNi/g Adsorption amount at 298K varies from 16.36mgNi/g for initial solution concentration of 100mg Ni/l to 47.93mg Ni/g(for C0=400mgNi/L) and it increases at 333K to 16.65 mgNi/g and 51mgNi/g (for C0=100 and 400 mg Ni/L )respectively. The adsorption of Ni(II) ions was increased by increasing PH up to ~ 5 and then stabilized up to PH=6 and after that the precipitation process was accured.
In this search, the removal of copper and lead ions from aqeous solutions by flotation had been studied, and the effect of various factors on the removal process. The study showed that the removal of copper and lead ions was increased by increasing the value of the solution pH up to pH = 8 and the removal rate was 80%. At pH = 10 precipitation of the ions was obtained in the form of hydroxides. The removal ratio of both ions is increased by increasing the flow of the air within the solution to reach 98% for copper and 97% for lead at the flow of Q = 1000 ml/min and then the removal rate decreases to 60% with increasing airflow to Q = 1500 ml/min. The initial concentration values affect the removal process and the increase in the removal ratio was shown by increasing the initial concentration. The removal rate of copper ions was 50 % at the initial concentration of C0 = 50 mg / l to 98% at C0 = 100 mg / l. While the lead removal rate was 61 % at the initial Concentration C0 = 50 mg/l to 97% at concentration C0 = 100 mg / l.
In this work the use of natural magnetite in coast sand of Wadi-kandil area in Syria in removal of Methylene Blue (MB) from aqueous solution was studied. The XRD measurements showed that the sample contents the crystalline magnetite and another co mpounds. The magnetite in the simple was separated using magnetic method and the percentage of magnetite in the sample about 70 %. After separating the magnetite was used to removal the MB from aqueous solution at different initial concentration of MB (5 , 10 , 20 , 40 , 60 mg/l ) and using different dosage of magnetite (0.2 , 0.5 , 1 g) at different values of pH and temperature 25° C. The adsorption of MB increasing by increasing initial concentration of MB and decreasing by increasing of pH value and the removal of MB was clearly increased when the dosage of magnetite was increased , the removal values were 47.8% , 84.9% , 88.7% for magnetite dosage (0.2 , 0.5 , 1 g) respectively at concentration 5 mg/l of MB . While the adsorbed amount of MB per mass unit of magnetite was decreased because the adsorption sites weren't saturated. The Treatment of adsorption data according Lngmuere and Frenglish models showed that the adsorption process accrued on the energetic homogeneous and heterogeneous sites.
Many chemical compounds (bases, inorganic acids, salts) have been used to find a suitable solvent for vanadium oxide And determine optimal conditions for its Dissolution.The best of them was sodium hydroxide at 2M concentration. The solubility was 100% at 90 °C and the solubilitys time was 30 min. The number of motor cycles was 800 cycles / min and the liquid / solid ratio was 200 g / L. In addition,the best amino protonadted compounds were used to precipitate vanadates from their solutions (monoethanolamine, diphenylamine, hydrazine, hydroxide amine hydrochloride, urea) with several inorganic acids (HCl, H2SO4, HNO3) and 1: 1 acid/base was monoethanolamine protonated with concentrated sulfur acid .
The possibility of using tuff and modified Jordanian naturalzeolite to remove the iron ions, a model component of heavy metals in underground water, off aqueous solution were studied. Bench-scale process was used to remove the iron ions off standar d solutions and real under ground water. Different parameters affected the ion exchange have been investigated, such as concentration, modifier type and PH. Zeolite characterizations weredetermined as XRD, XRF, BET, TGA, andFTIRmethods.We found that the modified zeolite with sodium chloride had more effect than other salts and the iron ions exchange efficiency depends on concentration.Zeolite efficiency was affected by PH value. Time of sorption equilibrium achieved within 250 min. The results agree with Langmuir model.
