Fotokatalyzátory a jejich funkce při odstraňování dusitanů a dusičnanů ve vodách

Abstract

The present thesis discuss the verification of knowledge and literary study of nitrite and nitrate removal from water by photocatalysis. The thesis tested the influence of quantity of photocatalyst, the effect of nitrite and nitrate concentrations, pH influence and the influence of organic modifier. Tests were carried out for classical photocatalyst P 25 and TiO2 bound to kaolin. For evaluation purposes of experiments were some analytes tested for the suitability of various analytical procedures. The theoretical part is an analysis of the problem. The experimental part deals with various practical experiments for the verification of previously acquired knowledge. Details of literary research are confronted with the measured data.
