Possibility of use of the fulfilled kieselguhr for sewage treatment from copper

In article influence of various ways of drying and thermochemical activation of the fulfilled diatomaceous earth on process of sewage treatment from copper is considered. Researches have shown that the adsorptive properties of the fulfilled diatomaceous earth and extent of removal of copper from sewage increase at increase of temperature of drying. Thermochemical activation allows to increase the adsorptive properties of diatomaceous earth. The adsorptive properties of the fulfilled diatomaceous earth depend on concentration of the sodium hydroxide used for activation, duration of thermal influence and a ratio the fulfilled diatomaceous earth/sodium hydroxide. Results of researches demonstrates that the fulfilled diatomaceous earth after thermochemical activation can be applied to sewage treatment from copper. Efficiency of purification of model solution of sewage of copper when using of the fulfilled diatomaceous earth subjected to thermochemical modification with sodium hydroxide reaches 98,70 %.
