A cross linked polymer was synthesized by condensation reaction between polyacrylic acid with succinic acid dihydrazide in the presence of phosphorus oxychloride. The products were characterized by FTIR. The resulted polymer has high rigidity and easily grinded, with high stability.This polymer was used as stationary phase for HPLC. This stationary phase has been packed into stainless steel column. The chromatographic performance of the newly packed column was characterized.

Hypertension (HT) And related diseases such as chronic kidney disease(CKD) share in that one of the main reasons for them is to increase the oxidative stress, which in turn increases the severity of the disease and exacerbation of symptoms. Reactive molecules produced from oxidative stress, in addition to causing tissue damage by oxidation of biomolecules like DNA, lipids, proteins and sugars; they are lead to the formation of mediators with potent inflammatory effect.

 In this research study, the photobleaching (photocatalytic degradation) of two dyes namely; Eriochrom Black T (EBT) as anionic dye and Methyl Violet (MV) as cationic dye have been investigated using
