摘要: 土壤自溶液中吸附MoO42-会影响植物生长[1]。前人对这一吸附过程已作过一些研究[2-5]。本文报导阴离子表面活性剂十二烷基硫酸钠(SDS),阳离子表面活性剂氯化十六烷基吡啶(CPC)和非离子表面活性剂吐温-20(TW-20)对Al2O3吸附MoO42-的影响。 实验所用吸附剂为层析用中性Al2O3(上海五四农场化学试剂厂),SDS(化学纯,广东石岐化工厂),CPC(化学纯。上海试剂一厂),TW-20(试剂级),其余试剂均为分析纯,含钼液用Na2MoO4配制。

Abstract: Adsorption of MoO42- on the neutral alumina has been carried out with the addition of anionic surfactant sodium dodecyl sulfate(SDS),cationic surfactant cetyl pyridine chloride (CPC) and non-ionic surfactant TW-20. It is found that the amount of the adsorbed MoO42-changed with pH value of the solution, and SDS, TW-20 decrease the adsorption,but CPC increases it.
