摘要
采用NaCl-溴水为溶剂、封闭溶样法分解试样,泡塑抽滤吸附以及碘量法测定矿石中Au。方法简单快速、准确、不污染环境,适用于测定矿石中0.x~xxg/t的Au。
he gold is enriched by the use of polyurethane foam after sodium chloride-bromine waterdissolution in closed atmosphere. The method is nonpolluting and is simple and accurate. Gold of(0.x~xx)×10 ̄(-6)levels can be determined by the method which gives satisfactory results.
