A new activated adsorbent developed for fluoride removal was investigated. The adsorbent was characterized for its high selectivity for fluoride, great adsorption capacity, applicable in neutral media and much better adsorption effect at high temperature. The mechanism of removing fluoride is a typical chemiad-sorption, differ from that of activated alumina. It was showed from the results of column test at a geothermal well that the breakthrough volume is 2380 and approximately 4000BV at the criteria of 1.0 and 3.0 mgF/L in treated water respectively. The content of fluoride ions in the geothermal water is up to 8.0 mg/L. It was showed from the results of on-the-spot tests for drinking water that the adsorbent not only plays a part of removing fluoride, but also has notable effects of reducing turbidity, decolorizing, dealkalizing and removing iron ions for drinking water.

The effect of magnetic fleld on magnetic adsorbent adsorbing Cu 2+ was studied through the adsorption experiment. The results showed that the adsorption amount of magnetized adsorbent is bigger than the unmagnetized one and the adsorption amount of the adsorbent increases with the increase of the magnetic fleld intensity. The equation of magnetized adsorption equilibrium relationship can be described with that Freumdilich isotherm equation. The breakthrough adsorption amount of the magnetic adsorbent adsorbing Cu 2+ increases with the increases of the magnetic field intensity. The breakthrough adsorption amount and the breakthrough volume are related to the concentration and flow rate of Cu 2+ solution at inlet.
