Spectrophotometric determination of ceterizine hydrochloride with Alizarin Red S.
A simple, rapid and sensitive spectrophotometric method has been developed for the assay of ceterizine hydrochloride (CTZH) in bulk drug and its pharmaceutical preparations. This method is based on the ion-pair complex reaction between CTZH and Alizarin Red S in Clarks-Lubs buffer. The chromogen being extractable with chloroform, could be measured quantitatively at 440 nm. All variables were st...
متن کاملComplexation of L-arginine and L-lysine by p-sulphonatocalix (61 arene in aqueous solution at different temperatures
The interaction of p-sulphonatocalix [6] arene towards L-arginine and L-lysine has been studied inacidic aqueous solution (p1-1 2) using UV-Vis spectrophotometric titration technique. The psulphonatocalix[6] arene was found to be able to form 1:1 complexe with amino acids in water.The values of the association constant were determined at different temperatures to evaluate thethermodynamic funct...
متن کامل“Removal of Alizarin Red-S Dye from Aqueous Solution by Sorption on Coconut Shell Activated Carbon”
The removal kinetics and mechanism of alizarin red-s dye, adsorptions on coconut shell activated carbon [CSAC] is studied. The use of low cost ecofriendly adsorbent has been investigated as an ideal alternative to the current expensive methods of removing the dye from aqueous solution. The adsorption removal of Alizarin Red-S dye on CSAC was investigated using batch adsorption technique. The di...
