Microextraction with smartphone detection of thiocyanate in saliva of tobacco smokers using paper‐based analytical method
Rebwar Omar Hassan
Abstract:This study presents a novel, cost‐effective approach involving spectrophotometric and smartphone paper‐based (SPB) methods and a distinctive salting‐out air‐assisted dispersive microextraction procedure to quantify thiocyanate in saliva samples. The method relies on the inhibitory effect of thiocyanate on quinoneimine dye formation during the Emerson reaction with sodium hypochlorite. Spectrophotometry quantifies the extracted dye by monitoring quinoneimine color intensity reduction at 525 nm. In the SPB metho… Show more
