Estimation of selenium(IV) in human hair, nails, blood samples and wheat and jaggery samples using morpholine dithiocarbamate

A rapid, highly sensitive and selective spectrophotometric determination of selenium (IV) is studied. The maximum absorption of the selenium morpholine dithiocarbamate complex in chloroform is at 350 nm in sodium acetate-acetic acid buffer medium of pH 4.0. The formed complex has a stability of 12 hours. Interference due to various cations and anions has been investigated. The optimum reaction conditions and other analytical parameters are reported. The proposed method has been applied to detect the levels of selenium in human hair, nails, blood samples and jaggery and wheat samples
