摘要
A mesoporous zirconia film was simply introduced to coat coal cinder by means of sol-gel technique. Zirconia coated coal cinder was employed in removal of As(III) and As(V) from aqueous solution followed inductively coupled plasma atomic emission spectrometry detection. At NaOH/HCl medium, both As(III) and As(V) can be quantitatively adsorbed at a wide pH range of 2.0-9.0. Adsorption process followed well pseudo-second order rate kinetics and Freundlich isotherm equations. The maximum adsorptive capacity of the coated coal cinder for arsenic was 95.7 mg g(-1).
