Study on oxidative degradation of HPAM and CPAM;

The oxidative degradation of sulfadiazine at the interface of α-MnO_2 and water;

Kinetics of sodium lignosulfonate oxidation degradation by dielectric barrier discharges

The resultsreveal that K 2 FeO 4 isa strong oxidant,the rate of oxidation degradation of PAM isabove90%in60min,the effect of viscosity-breaking isalso very obvious,and the viscosity of oilfield sewage containing PAM isdecreased to the sam.

It is studied the oxidation degradation of chitosan with H 2O 2 under neutral condition.

To determine the optimum degradation condition of Marine Sulfated Polysaccharide 916,taking the yield of molecular as marker,orthogonal test was used to evaluate the influence of 3 factors,including the concentration of H2O2 solution,the reaction time and the concentration of material.

The degradation technologies were optimized as followings: the ratio of diterpenoids to 1,2-propanediol was 1%,air feed rate was 5 L/h,reaction temperature was 160℃ and reaction period was 2 h,respectively.
