Adsorption behavior studies of Cerium on modified Mesoporous Aluminosilicate
In this paper, the adsorption of cerium on modified Mesoporous aluminosilicate (with Si/Al mole ratio of 10) was studied. The effects of pH, contact time, initial concentration of cerium on adsorption of cerium were investigated. The adsorption capacity was high in the pH range of 4-8 and decreases with decreasing of the pH value. The Langmuir and Freundlich isotherms were applied to represent ...

متن کاملDetermination of ranitidine using potassium iodate and dichlorofluorescein
Two methods for determining ranitidine hydrochloride (RNH) in pure drug and in formulations using potassium iodate and dichlorofuorescein are described. Titrimetry involves the oxidation of RNH by a known excess of potassium iodate in acidic conditions followed by iodometric determination of surplus iodate. In spectrophotometry also, the drug is oxidized by a large excess of iodate and the iodi...
متن کاملImproved method for measuring hydrolyzable tannins using potassium iodate
Until now, the recommended procedure for measuring hydrolyzable tannins has been to mix the reagent and sample, subject the mixture to a certain amount of chill, allow the reaction to continue for some time at a higher temperature and then measure the absorbance of the colored solution. The effect of different chill conditions has been studied by many workers but the effect of conditions after ...
