Application of Magnetite Zn/Al Layered Double Hydroxide (Fe3O4 Zn/Al LDH) on the Removal of Organic Matter in Supplying Water

Abstract

In this study, magnetite Zn/Al layered double hydroxide (LDH) composite has been synthesized through the chemical co–precipitation method. Raw water samples of Thu Duc and Tan Hiep water plant were also collected and analysed, they were used as the object to investigate dissolved organic compounds (DOC) adsorption capacity of the material. The results of DOC empirical adsorption experiments in raw water samples of Thu Duc and Tan Hiep water plants also show that the adsorption processes reach high efficiencies when the sample solutions are adjusted to pH from 5 to 6. After 21 hours, the adsorbent in column loses its adsorption ability with the corresponding adsorption capacity of 8.12 mg/g.
