Hyrdride Preconcentration for Inductively Coupled Plasma Optical Emission Spectrometry.
Abstract
Studies are presented describing an improved application of the NaBH4 reduction of soluble arsenite to form arsine as a preconcentration approach for ultra-trace level arsenic determination by inductively coupled plasma optical emission spectrometry (ICP-OES). Specialized analyte introduction techniques are described for elimination of reaction by-products that would normally extinguish a medium power plasma discharge. An approach is presented to minimize the need for back ground correction and facilitate a superior arsenic detection limit (< or = 0.03 ng/mL) in a relatively inexpensive 1.2 kW ICP system. (Author)
