摘要
氮、磷、钾肥料对高吸水树脂吸水率具有很强烈的影响。硫酸铵、硝酸铵、碳酸氢铵,过磷酸钙,氯化钾、磷酸二氢钾,硫酸钾、铵磷钾肥使高吸水树脂吸水率为0的浓度分别为10%、10%、10%、1%,15%、5%,15%,5%。尿素即使在饱和浓度下,高吸水树脂仍保持在65%以上的吸水率。1克高吸水树脂在标准吸水范围内对上述肥料的最大吸附量分别是1.14,1.21,0.49,1.15,0.35,108.61(克),氮、磷、钾肥料浓度与高吸水树脂吸水率、肥料吸附率存在显著相关关系。
N、P、K fertilizers affected the rate of absorbing water of high water-absorbing synthetic resin intensely.When the concentration of ammonium sulphate,ammonium nitrate,ammonium bicar bonate,calcium superphosphate,potassium chloride,potassium sulphate,potassium dihydrogen phosphate ammo-phos-ka was 10%,10%,1%,10%,15%,15% 5%,5% respectively,the rate of absorbing water of the resin droped to zero.When the concentration of urine was in saturation,however,the rate of absorbing water of the resin was stile more than 65%.In the standard range of absorption of water (resin:water= 1:1000),the maximum that the resin of one gram absorbed the above fertilizers was 1.14,1.21,1.15,0.49,0.35,108.61 grame respectively.The concen- tration of N,P,K fertilizers was obviously correlated with the rates of absorbing water and absorbing fertilizers of the resin.
