A Rapid and Simple Spectrophotometric Determination of Traces of Chromium ( VI ) in Waste Water Samples and in Soil samples by using 2-Hydroxy , 3-Methoxy Benzaldehyde Thiosemicarbazone ( HMBATSC )

Abstract

A rapid and simple Spectrophotmetric method has been developed for the determination of microgram amount of Chromium (VI) in aqueous dimethyl formamide (DMF). Chromium (VI) forms a yellowish green coloured M:L complex with 2-hydroxy-3-methoxy benzaldehyde thiosemicarbazone in the acidic buffer medium (pH=6.0) at room temperature. The complex shows maximum… (More)
