等浓度

It was rev ealed that:cuprite,malachite and tenorite are the three main kinds of copper-bea ring minerals which would be supersaturated when Cu concentration in the solutio n is high enough(higher than 0.0016 mol/L,0.0079 mol/L separately) under the stu dy conditions.Copper exists in the solution mainly as the species of CuCO3 ,Cu2+ and CuOH+.The corresponding content of CuCO3 would be decrea sed following the deposition of the copper-bearing minerals,nevertheless,Cu2 + and CuOH+ would be increased.

模拟结果表明，在土壤中常见的E h和pH及研究区的年平均温度条件下，溶液中铜离子的含量达到一定的浓度时，可以生成赤铜矿(当Cu≈00016 mol/L)、孔雀石及黑铜矿(当Cu≈0 0079mol/L)等次生矿物，溶液中Cu的存在形式也发生了变化，即CuCO3所占的比例不断减小，而Cu2+和CuO H+的含量则相继增高，且Cu2+的增幅大于CuOH+。
