摘　　要：实验研究了腐殖酸钠混合液对钙、镁离子的吸附性能。高温条件下由草炭和NaOH制取的腐殖酸钠混合液,吸附水中的钙镁离子,结果发现:随着混合液用量的增加,其对钙镁离子的去除效率增加。当混合液用量为8 ml时,二者的吸附效率均在88%以上,其中对镁离子的去除率可达100%,而且由于钙镁离子具有相同的核外电子层结构及类似的化学性质,因此混合液对钙镁离子的去除效果类似,表明腐殖酸钠混合液对钙镁离子具有极好的去除效果,可广泛应用于处理含钙镁离子的污水。This study took a research on the adsorption effect of sodium humic - acid solution on the Ca^2＋ and Mg^2 ＋. The solution made from turves and NaOH under high temperature was used to adsorb Ca^2 ＋ and Mg^2＋ , and the result indicate that the adsorption efficiencies of Ca^2＋ and Mg^2＋ increased as the dosage of the sodium humic acid solution increased. The adsorption effect reached higher than 88% , 100% for Mg^2＋ , especially under the dosage of 8ml sodium humic aicd solution. Further more since the uniform structure of the ions layer and the similar chemical property, the adsorption character to Ca^2＋ and Mg^2＋ was similar. The experiment result indicated sodium humic solution had a better removal effect to Ca^2＋ and Mg^2＋ and can used to treat wastewater containing Ca^2＋ and Mg^2＋ widely.
