摘要： 建立了偶氮胂Ⅲ分光光度法测定化妆品中锆的含量。考察了显色剂用量、显色时间、显色温度以及共存离子对吸光度的影响,优化了测定条件。结果表明,室温下显色30 min,吸收波长664 nm处,锆的线性范围为2～10 mg/L,相关系数R2＝0.999 9,方法检出限为59 mg/kg,定量限为72 mg/kg,RSD=3.23%,回收率为88.8%～109.2%。常见共存离子K+、Na+、Ba2+、Sb3+、Pb2+等对测定锆无干扰。该方法可靠、准确,适用于化妆品中锆的测定。

Abstract: An arsenazo Ⅲ spectrophotometric method for determining zirconium content in anti-perspiration cosmetics was established.The effects of dosage of chromogenic agent,time and temperature for chromogenic action,as well as the coexisting ions on the absorbance were investigated.Results showed that under room temperature,absorbing wavelength of 664 nm and 30 min for chromogenic action are the suitable conditions.The linear range for zirconium content is 2~10 mg/L and the correlation coefficient R2 is 0.999 9;the detection limit is 59 mg/kg;the limit of quantification is 72 mg/kg;RSD achieves 3.23%;the spiked recovery achieves 88.8%~109.2%.Common coexisting ions,such as K+,Na+,Ba2+,Sb3+,Pb2+ and so on show no interference to the determination of zirconium.The method is reliable,accurate and suitable for the determination of zirconium in cosmetics.
