Research progress on natural degradation of linear alkyl benzene sulphonate in environment;

Natural degradation is the main way of removing organic pesticides in soils.

The progress on research status and method of natural degradation is summarized, and some critical discussion in experimental design is described from the point of biodegradation and photodegradation.

The application of auto-degradated drilling fluid in water well works;

Study on Photochemical Degradation Properties of the Alkyl Xanthogenate Flotation Collecters;

Screening and identification of atrazine degrading bacteria and their degradation characteristics from black soil in cold area;

Isolation and degradation characteristics of high effective Cypermethrin-degrading microorganisms from tea garden soil

This paper focused on the separation,filtration,identification and degradation characteristics of the two strains L1 and N8 that were isolated from the sewage discharge outlet in Jilin Pesticide Factory and the leachate of the Changchun Peijia Landfill.

The degradation of PDLLA/HA hybrid material in normal saline was explored,and the corresponding products were characterized by FT-IR,TEM and XRD.

The results of measurement of the properties shows that the brittleness of chitosan films is considerably improved, and the rate of degradation of connect films by caprolactone is reduced.
