摘要
建立了以X-5大孔吸附树脂为脱色剂，依据IUC-18标准来测定深色革中Cr（Ⅵ）含量的方法。试验表明：对深色革提取液脱色率可达90％，而对Cr（Ⅵ）吸附率小于5％，当Cr（Ⅵ）浓度在3．368～33．68μg／L范围时，回归方程C=-0．1817＋584．4△A（r=0．9999）。样品加标回收率为91．3％～96．2％，相对标准偏差为3．59％～6．85％。
An analytical method of determination of Cr（ Ⅵ ） in deeply - dyed leather by using X - 5 macroporous adsorption resin for IUC - 18 was established. The results showed that the decolorization rate of solution reached 90% and the adsorption rate of Cr（ Ⅵ ） was below 5 %. Within the concentration range of 3. 368 -33.68 μg/L, the linear regression equation was C = -0. 181 7 ＋ 584.4 a △ （ r = 0. 999 9 ）. The recovery rate of sample was 91.3 % - 96.2% and the RSD was 3.59 % - 6.85 %.
