eurjchem-2002	Baker, Hutaf Mustafa; Alsaoud, Hussam Ahmad; Abdel-Halim, Hamzeh Mohamad	Spectrophotometric method for determination of ranitidine hydrochloride in bulk and in pharmaceutical preparation using ninhydrin	2020	7	.pdf	application/pdf	5125	274	55	Effect of initial concentration of ranitidine hydrochloride The effect of initial concentration ranitidine hydrochloride was studied under the optimum conditions and the results are illustrated in Figures 7 and 8, as we see from these figures, the values of absorbance increased by increasing the concentration of RNH until reaching the plateau, 2.816×10-4 M of RNH found to be sufficient to form stable complex with high intensity color. Effect of ninhydrin initial concentration The effect of concentration of ninhydrin was studied using various concentrations of ninhydrin keeping the concentration of RNH constant.	cache/eurjchem-2002.pdf	txt/eurjchem-2002.txt
