Water Absorption Ability and Water Activity of Konjac Superabsorbent Polymer
摘要
Abstract
The effect of the grain size of the konjac superabsorbent polymer（KSAP）,the pH of the solution,the different kinds of fertilizer on the absorbent ability was studied,and water activity of different water absorbenct gel was measured and compared with that of root.A preliminary application in water conservation forestry was also attempted.The results indicated that the water absorption ability of the resin was the best at the pH value 6-8 and the grain size about 1 mm.The effect of different fertilizers on the water absorbent ability of KSAP followed the order of（NH4）2SO4〉KH2PO4〉Na2SO4 〉KNO3〉KCl（NH2）2CO〉（NH4）2SO4donized water.When KSAP water absorption was greater than 100 folds,the water activity is higher than that of plant roots,suggesting KSAP can not only provide adequate moisture for plant growth but also effectively slow down the natural loss of moisture and evaporation.关键词
