摘　　要：本文绘出了利用活性炭自溶液中吸附Au（Ⅲ）及改性试验结果。在溶液酸度CH+=2～3mol·L-1时活性炭的吸附能力较强，经NH3·H2O、苯胺等改性后的活性炭增强了对Au（Ⅲ）的吸附作用，回收率可达98．0％。This essay focuses on application of the activated carbon to draw Au (Ⅲ ) from solution,and the result of modified experilnent. The drawing power of the activated carobon becomes stronger when the acid degrce of solution is CH+ = 2～3mol·L-1. While the activated carbon is modified with aniline、 ammonia water, Its drawing power can be stronger, its recorery rate may reach 98. 6%.
