摘　　要：用聚丙烯酸钠吸附含钾溶液,考察了吸附剂种类和用量,钾溶液浓度,时间,温度,pH值对吸附含钾溶液的影响。结果表明,当浓度为0.020mol/L,时间为60min,吸附温度为40℃,pH值为7,0.1g:100m L(kl-5a SAP:溶液体积)时,负载K+效果相对较好可以达到85%左右,很大程度上保留了溶液中的钾离子,可以填充土壤层用于减少钾离子流失。In this paper, the effect of adsorbent type and dosage, potassium solution concentration, time, temperature and ph on adsorption of potassium - containing solution was investigated by using sodium polyacrylate to adsorb potassium solution. Results showed that when the concentration of 0.020mol/L,60min,adsorption temperature is 40℃, pH = 7,0.1 g： 100mL （kl -5a SAP： the volume of solution）, the load about effect of potassium ions is relatively good at 85%, to a large extent retained the potassium ion in solution, it can fill the soil layer is used to reduce the loss of potassium ions.
