巯基棉对许多金属离子有较强的吸附能力,控制不同的酸度能选挥性地吸附或洗脱某些离子。在0.5—3N盐酸度下,巯基棉能定量吸附砷(Ⅲ),并能被温热浓盐酸洗脱,然而对较大量的砷洗脱率甚低。作者试验过含小量过氧化氢的温热浓盐酸可
Sulfhydryl cotton adsorption of many metal ions have a strong ability to control the different acidity can be selected to selectively swing or adsorption of certain ions. Sulfhydryl cotton adsorbed arsenic (Ⅲ) quantitatively at 0.5-3N HCl, and was eluted by warm concentrated hydrochloric acid. However, the elution rate of arsenic was relatively low. The authors tested warm concentrated hydrochloric acid containing a small amount of hydrogen peroxide
