摘  要:
[目的]研究丙烯酸系高吸水性树脂(SAP)对微肥中不同盐类吸持作用。[方法]采用自然过滤法测定树脂吸水率,采用火焰原子吸收分光光度法测定树脂对锌、铜微肥等的吸肥量。[结果]树脂在不同盐水溶液中吸水率的大小顺序为:(H2O)>MnSO4≈CuSO4≈ZnSO4>FeSO4。[结论]微肥中各种盐类降低了树脂吸水率,同时对各种微肥有一定的吸持作用,其吸肥量随微肥浓度增大而增加。

摘  要:
[Objective]The aim was to study the fertilizer retention capacity of water superabsorbent polymers of acrylic acid series.[Method] The capacities of absorbing water and retaining Zn and Cu in fertilizer of the polymers were studied using natural fitration and FAAS.[Result] The order of water absorbency of the copolymer in different solution was(H2O)>MnSO4≈CuSO4≈ZnSO4>FeSO4.[Conclusion] The microelement fertilizer decreased the water absorbency of the copolymer.Meanwhile,the fertilizer retention capacity of the copolymer increased with the increase of the concentration of the fertilizer solution
