A simple and sensitive method is proposed for the spectrophotometric determination of drugs, viz. isoniazid, trimeprazine tartarate, pyridoxine HCI and captopril based on their reactivity with potassium bromate. The method involves the addition of excess KBt03 of known concentration in the presence of 0.7M HCl and the unreacted KBr03 is determined by the measurement of the decrease in the
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
