Experiments are conducted on the effect of different types and different molecular structures of polymers on HPAM removal existed in solution or sewage. It is found out that only cationic polymer has a better removal effect of HPAM among the non-ion, amphoteric ion and hydrophobical cation polymers, especially the DMDAAC cationic polymer has an optimal result. The removal capacity to HPAM can be further improved by using appropriate molecular weight and cationic capacity and gas floatation technique.

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.
