腐植酸基-粉煤灰型保水剂概述
Summary of Humic acid base-Fly ash superabsorbent polymer
高吸水性树脂由于其高吸水性和很强的保水性被广泛用于医疗卫生、建筑、植树造林等方面，其中在土壤中的应用倍受关注[1-2]。煤炭中的腐植酸作为一类储量极为丰富的天然大分子，在促进植物生长方面有显著的作用[3]。粉煤灰有吸水性，继承了古代植物中多种养分元素，可明显改良土壤理化性质[4]。合成一种加腐植酸和粉煤灰的保水剂能促进植物的生长，改善土壤的理化性质，同时能降低树脂的合成成本，有较好的经济和利用价值。
Super absorbent polymers because of their high water absorption and a strong water-holding capacity are widely used in medical and health, construction, afforestation, etc., of which the application in the soil has drawn greater attention. Of coal humic acid as a class of very rich reserves of natural macromolecules, in promoting plant growth has a significant role.Fly ash has water absorption and inherit kinds of nutrient elements from archaic plants ,so it can improve soil physics and chemistry character. Synthesizing the humic acid and fly ash in foundation of the PSA-AM can promote plant\
