| Abstract: | The mechanisms of influential factors in degrading waste chitosan solution by Fenton reagent were investigated.The optimal operating conditions determined by monofactorial analysis and orthogonal experiment are as follows:p H( initial) =2 .5,p H ( end) =1 0 ,t( stirring time) =6 0 min,t( static time) =8hrs,T( temperature) =348K and the dosages ofFe2 ]( 1 0 g Fe/L) andH2 O2 ]( 30 % ) are1 5m L and2 m L respectively. The COD removal efficiency under the optimal condition is 58.91 % .Under the fixed condition,the degradation efficiency of Na Ac with Fenton reagent was studied at room temperature.The highest degradation efficiency can reach 1 6 .39% . |
