The results showed that the structure of St-g-PAM was meshy,and porous,and integrant linetype,the soluble starch had elliptic form,and PAM was linear color;the crystallinity of St-g-Pam had been improved,and was better than PAM;the thermal stability of St-g-PAM was also better than PAM,which was the significant reason that the graft polymer had the ability of excellent flocculation.

线型St-g-PAM作为一种新型的高分子絮凝剂，它结合了淀粉与聚丙烯酰胺的特性，广泛应用于废水处理、石油化工、造纸工业等领域[3~5]。由于其原料淀粉来源丰富、价格低廉，且线型St-g-PAM的成本比PAM低，故越来越受到人们的重视。

Results showed that the kinetics of photocatalytic degradation of ethylene by TiO2/ACF desoposited Pt in the simulated cold storage environment for horticultural products could be described using the pseudo first-order equation. The prepared TiO2/ACF-Pt, in the process of which Pt was initially deposited on the surface of ACF and then TiO2 was coated, would promote the activity of ethylene decomposing. When ion sputtering time was 60 seconds (Pt/Ti atomic concentration ratio was 0.112), the apparent rate constant of the reaction of TiO2/ACF-Pt was 1.16 times as much as that of TiO2/ACF. The micrographic structure of ACF was not damaged and an excessive porous structure, which was contributive to absorbing the diluted ethylene, was obtained by the way of ion sputtering Pt.

结果表明：在模拟园艺产品冷藏环境中，TiO2 /ACF-Pt光催化降解乙烯的动力学可用表观一级速率方程来描述；ACF表面先溅射沉积Pt，再进行TiO2附着方案，能提高降解乙烯的能力，当溅射时间为60 s（Pt/Ti原子浓度比为0.112）时，表观一级速率常数是未溅射Pt的1.16倍；TiO2/ACF-Pt的制备方法，对ACF形貌结构没有破坏，并能得到有利于对微量乙烯的吸附的多孔结构。
