Title A simple analytical technique for the determination of hexavalent chromium in welding fumes and other complex matrices.
Bibliographic information Dec. 1979, Vol.5, No.4, p.386-403. 26 ref.
Abstract The s-diphenylcarbazide method proposed by NIOSH permits less than 1% recovery of chromium(VI) from synthetic welding fumes of known composition. In the carbonate leaching technique presented, recovery of soluble and insoluble chromium(VI) is better than 80%. It is used as part of a general method for determination of the total chemical composition as distributed among sample fractions of different solubility. It is specifically designed for analysis of small samples and routine monitoring of the working environment.
