Spectrophotometric determination of arsenic with diethyldithiocarbamic acid silver salt and borohydride as reducing agent

Add time:09/07/2019    Source:sciencedirect.com

A modification of the Vasak and Sedivec method for the spectrophotometric determination of arsenic using borohydride as reducer was proposed. The absorption spectrum, fulfilment of Beer's Law, interval of application, and reproducibility of the method were all examined. Statistical and economic studies of the method were carried out. It is proposed that this method be applied in the determination of arsenic in soils.
