ABSTRACT
Objective To establish a method for rapid determination of the lead in air by water phase of solubilisation dithizone photometry. Methods The lead in air was determined by water phase solubilisation dithizone photometry with Tween20 as the solubilizer. Results The linear range was 1.0-100 mg/L(r≥0.999),RSDs were 1.36%~9.57%,the recovery rates were 97.4%-98.3%,the lowest detected concentration was 0.003 mg/m3. There was no significant difference between the result of this method and that of colorimetry. Conclusion The method was rapid,accurate and sensitive,this method is suitable for rapid determination of lead in the air.
