摘要
采用 Zn-EDTA掩蔽铁等干扰元素 ,在 p H5～ 6间 ,铝与铬天青 S生成水溶性的紫红色配合物 ,在波长 5 46nm处 ,进行光度测定。此法简便、快速 。
To cover up interference elements,such as Fe,etc,to react Al with chromazurol S to produce red composition with water solubility at pH5~6,its photometry is carried out at wave length of 546nm.This method is sample,quick and it can meet the requirments of production process.
