Abstract

The biosorption characteristic of Cd(II) ions from aqueous solution using Lengkuas Merah (Alpinia Gralanga) were investigated as a function of pH. The maximum biosorption capacity of a Lengkuas Merah (Alpinia Gralanga) for Cd(II) was found to be 18,37 mg/L and 91,85% at optimum pH was 10. At pH 2 to 10 the biosorption of Cd ions tends to increase. The result showed that the lengkuas merah  can be evaluated as an alternative biosorbent to treatment waste water containing Cd(II). A Lengkuas Merah is low cost and has considerable high biosorption capacity.
pH值对冷杉藻生物吸附离子Cd(II)的影响
研究了冷花花(Alpinia Gralanga)对Cd(II)离子的生物吸附特性与pH的关系,发现冷花花(Alpinia Gralanga)对Cd(II)的最大生物吸附量为18.37 mg/L,在最适pH为10时吸附量为91.85%。在pH值为2 ~ 10时,Cd离子的生物吸附有增加的趋势。结果表明,龙葵可作为一种可替代的生物吸附剂处理含镉废水。它成本低,具有相当高的生物吸附能力。
