Adsorption Effect of Iron-Aluminum Binary Oxide on Copper Ions

Abstract:

As its highly adsorption ability, iron-aluminum binary oxide (Fe-Al binary oxides) can adsorb heavy metals in the environment. The objective of this study was to tese the adsorption effect of Fe-Al binary oxide on heavy metal copper in different conditions. Result showed that with the temperature increased, the adsorption amount of Cu by Fe-Al oxides also increased. The experimental results can fitted well with Freundlich equation; When pH < 7, the adsorption quantity increased with pH increasing, when pH > 7, adsorption quantity is close to a constant value. At the beginning of the reaction stage (0~120 min), adsorption of Cu increased rapidly, then adsorption quantity of Cu gradually become smaller, and eventually reached balance.
