Synthesis of cation inartificial high moleculer and its flocculent performance |
| |
| Abstract: | We prepare the cation inartificial high molecular flocculent by starch with diallyldimethy ammonium chloride(DMDAAC).Different initiator of oxidize redoxsystem are studied. We find the optimum reaction condition: m(starch)/m(DMDAAC)=1∶4;concentration of monomer, 35%; concentration of initiator,0.8?mmol/L;pH,2-3;reaction temperature,50?℃;reaction time,6?h. Performance experiment reveals that the product has better flocculent effect. |
