Abstract
Magnetites (MEBWx) were prepared by precipitation in 1-butanol/water mixtures of various mole ratios of 1-butanol to water. It was found that the magnetites prepared in the mixture with high mole ratio of 1-butanol to water have high specific surface area. The adsorption isotherms of As(III) and As(V) with the magnetites at 303 K fitted the Langmuir model well. The adsorption capacities of the magnetite prepared in the mixtures were higher than those of the magnetite prepared without 1-butanol. Their adsorption capacities increased with increasing specific surface area.
