DETERMINING THE AMOUNT OF NICKEL IN BRONZE ON SOLID PHASE USING CATION EXCHANGER ON STRONG ACID
Journal of Chemical and Pharmaceutical Sciences / 1 - مارس - 2015
A method was designed for the determination the amount of nickel in bronze. It was based on the adsorption of nickel on positive ion exchange of strong acid Amberlit CG-120 in form–H. HCl:acetone medium at pH=1 was used in order to separate other positive ions as chloride complexes. The fluids were filtered and the cation exchanger was treated with ammonium buffer solution pH=8-9, then it was treated with an ethanolic solution of Dimethylglyoxime. The determination of Nickel content was carried out using a spectrophotometer. Results indicated a content of 0.29±0.02%, whereas the nickel theoretical content was 0.31%. Using IR spectra, it was found that the adsorption of nickel on Amberlit CG-120 was due to covalent bonds with groups-SO3-, in the form of ammonium complexes.

Journal of Chemical and Pharmaceutical Sciences / 8 - مارس - 2017
This study deals with developing a method to determine the impact of lead via the light spectrum in the solid phase. This method is characterized by selectivity, speed and ease in performing the analysis. It also allows secure detection of low (LOD) and high accuracy analysis (LOQ).
Determining the Concentration of Fluoride in some Water Bodies on the Syrian Coast using Fluoride Selective Electrode
Journal of Chemical and Pharmaceutical Sciences / 8 - مارس - 2017
This is a study of the concentration of fluoride in some water bodies on the Syrian Coast such as sea water, artesian wells, rivers, dams, wastewater and rain water. It offers a comparison between the concentration of Fluoride (F) standard of the World Health Organization (WHO) and that of the Syrian standard
