Abstract
Automatic equipment is used to generate tin hydride from sample solutions prepared by fusion of powdered rock with lithium metaborate followed by digestion with hydrofluoric and sulfuric acids. The evolved hydride is swept by argon into an electrically heated quartz tube atomizer. The atomic absorption of tin is measured at 224.6 nm. Oxalic acid and 1,10-phenanthroline are used to minimize interferences from iron, copper, and nickel. The detection limit of tin in the rock samples is 0.5 ppm. Results for reference rock samples agree closely with published values. A direct acid digestion procedure produces similar results for tin in many samples.
