摘要
A spectrophotometric method is suggested in order to determine the metals leached with HNO 3 on the polystyrene filter, on which air borne dust are collected with a low volume sampler.The method, which gives parallel results similar to AAS method and with the same accuracy, can reasonably be applied to routine analysis of Ni, Cu and Co in air borne dust in the workshop.
