内容記述(抄録等)
We have been developing multifunctional water purifying materials using change composition hydrotalcites. Copper containing and zinc containing hydrotalcites have been synthesized for the propose of disinfection wastewater and phosphorous removal at the same time. Four kinds of copper containing hydrotalcites (Cu-HT, 1-4) and zinc containing hydrotalcites (Zn-HT, 1-4) were synthesized by a coprecipation method. Removal characteristics of phosphate ions in solution for the Cu-HT and Zn-HT have been investigated from the various standpoints.
Apparent adsorption capacities of phosphate ions for the Cu-HT(1-4) and Zn-HT(1-4) were 20.9-31.9mg-P·g-1 and 14.4-21.8mg-P·g-1, respectively, near neutral pH values. Various anion selectivities for Cu-HT(4) and Zn-HT(1) were in the order of CO32->SO42->PO43->NO2->Cl->NO3-.
Taking the results obtained into account, Cu-HT (4) had high and stable phosphate ion adsorption capacities with wide range of phosphorous concentrations and pH lead to the conclusion that Cu-HT (4) has the feasibility as a removal agent for phosphate ions in wastewater. Moreover, Cu-HT (4) had disinfection potency which completely sterilized 106cells·ml-1 of E.coli with the contact time at 60min previous experiment, thus, Cu-HT (4) had been expected as a multifunctional wastewater purifying materials with both phosphorous removal potency and disinfection potency.
