香皂中常含有痕量铁.铁含量是影响香皂质量的重要指标之一.已有的方法用硫氰酸盐水相光度法测定,该法灵敏度低,稳定性差.本工作者采用树脂相光度法测定,灵敏度和稳定性均较高,获得了较满意的结果.
Soap often contains trace amounts of iron. Iron content is an important indicator of the quality of soap one of the existing methods of thiocyanate aqueous phase spectrophotometry, the method of low sensitivity and poor stability of the workers using resin phase spectrophotometry Measurement, sensitivity and stability are higher, get more satisfactory results.
