摘要
本文研究了大孔阴离子交换树脂从腐殖酸浸金液中吸附金的性质。结果表明,吸附过程以液膜扩散控制为主。实验测得吸附扩散系数K=1.96×10 ̄-4S ̄-1。实验还表明,溶液的pH值及温度越高时,树脂吸附金的速率越快。吸附过程可用Boyd方程表达。
The gold adsorption from leaching solution if humic acid by large aperture anion exchanse resin was studied. It was demonstrated that the adsorption process is mainly controlled by the dispersion of liquid film. Testing showed that the higher the pH value and temperature of the solution were, the greater the velocity of gold adsorption was. The dispersion coefficient of adsorption K= 1.96×10 ̄-4 see ̄-1 through determination in the test. The adsorption process can be expressed by the Boyd equation.
