Preparation Of Activated Car-Bon From Sludge Modified With Extracel-Luar Polimeric Substences

In this article we discuss about the Extracelluar Polymeric Substences (EPS) between particles of sludge. In the first step, we extracted EPS from sludge and studied the difference between adsorption properties of carbonized sludge of different sludge of different EPS amount. It proved that the carbonized product of EPS have a effect on both adsorption point and structure of carbonized sludge. And soluable EPS has more important influence than boned EPS.In second part, we use starch and fulvic acid to simulate sugar and humic in EPS. In this part, we discuss about the adjunction proportion, carboniuzed temperature and carbonized time. The addition of fulvic acid have a positive correlation with the adsorption capacity, while starch addition need to be added in a exactly right proportion so that it can have a slight improve in the adsorption capacity.We also use Cu2+adsorption, themo analysis and FTIR to discuss the change of starch and fulvic acid in the process of carbonization. The result of two different addition was test by adsorption of Cu2+, and it prove that addition of fulvic acid can improve the adsorption capacity.At alst, we get two type of carbonized sludge modified by adding starch and fulvic acid, which have Cu2+adsorption capacity of62mg/g and103mg/g.
