دُرست إمكانية تشكيل معقد ملون بين أيونات الحديد و الكاشف 4- هيدروكسي -3- 2- هيدروكسي فينيل ميثلن أمينو بنزن حمض السلفون بهدف استخدامه في تحديد معدن الحديد بالطريقة الطيفية الضوئية في محاليمو المائية، لقد تبين أن الكاشف المذكور يشكل مع الحديد الثنائي معقداً مموناً بالمون البرتقالي في وسط مائي. دلت الدراسة التجريبية لطيف امتصاص محلول المعقد المتشكل، أن طول الموجة الموافق لامتصاص أعظمي, و عند هذا الطول الموجي الأعظمي تمّ تحديد كافة القرائن الكمية المتعلقة بهذا المعقد.
The possibility of formating a colored complex between Fe2+ ions and 4-Hydroxy-3- [[(2-hydroxy phenyl) methylene] amino] benzene Sulphonic Acid (HVMAB) was studied spectrophotometric method for determination of iron in aqueous solutions. The reagent reacts in aqueous medium at pH=5 to give an orange complex with maximum absorbance λmax=415nm.

A Simple, accurate and highly sensitive spectrophotometric method have been
developed for the rapid determination of Ofloxacine (OFX) in pure form and
pharmaceutical formulations. The visible spectrophotometric method was based on the
formation of
a Orange Yellow colored complex between the (OFX) and 2-amino-6-
nitrobenzothiazole (ANB) at pH 5.2 and 80±5 ºC in 5 min., and λmax at 440 nm. The
effects of analytical parameters on the reported system were investigated. Beer's law was
obeyed in the concentration range of 1.80-86.72 μg/mL, with a percentage relative standard
deviation not exceed ±2.54 and the molar absorptivity coefficients was 3.952×103
(L/mol.cm). Interferences of the other ingredients and excipients were not observed, the
results showed that the developed method with the accuracy and sensitivity highs.
A sensitive, simple, selective spectrophotometric method has been developed for determination Cobalt (II) with 1-(2-pyridylazo)-2 naphthol (PAN). This method ralies on the formation of stable red colored complex at pH=4.1 which has an absorption maximum at 580nm.
Simple, accurate and reliable spectrophotometric method
has been developed for the quantitative determination of
Cephalosporins: Cefaclor, Cefalexin, Cefadroxil in pure and
pharmaceutical formulations. The method is based on the
determination of that in aqueous medium pH=6.45 at
25±0.5ºC.
A new, simple and sensitive kinetic spectrophotometric
method has been proposed for the determination of tropicamed
(TPC) in pure and pharmaceutical formulations. The method is
based on oxidation TPC by potassium permanganate in strong
alkaline m
edium (pH=12) to form green colored product with
absorbance maximum at 610nm.
In this work the process of removal of zinc ions from aqueous solutions was studied using natural Syrian zeolite. Two samples were used: natural zeolite Z and modified zeolite with NaCl solution Z-Na. The removal percentage of zinc ions vs. time was
determined using differential initial concentrations of Zn+2: 50,100,200,300,400 mg/L. The contact time was determined and it was 360 min. The removal of Zn+2 ions as a function of temperature and pH have been studied. It was found the increasing of removal percentage by increasing temperature and increasing when pH increasing up to ~7,then the precipitation of zinc hydroxide accurse. The Langmuire adsorption isotherm equation used to calculate the maximum sorption capacity and it was 21.7 and 28.5 mg/g for Z and Z-Na respectively. Results indicate a significant potential for the natural and modified zeolite as an adsorbent/ion-exchange materials for heavy metal removal.
