| Abstract: | Objective The method for the determination of deleterious elements （lead,cadmium,mercury and cooper） in inorganic pharmaceutical raw materials by atomic absorption spectrometry was established. Methods Lead and cadmium were determined by graphite furnace method,mercury by cold absorption,copper by flame method. Results Standard curves were showed good linear; correlation coefficients （r） were greater than 0.99; recovery rates were 90.0%-100.0%; each RSD was less than 7.0%. Conclusion The method is specific,simple and sensitive. It can be used in the limit control for harmful elements of inorganic pharmaceutical raw materials. |
