The present survey highlights for the first time that glucamine-modified ordered mesoporous silica (OMS) type SBA-15 can be used as adsorbents for the uptake of boron from water. By means of X-ray diffraction, N-2 adsorption-desorption, thermogravimetry and Fourier transform infrared, the structure and physicochemical properties of the materials were characterized. The behavior of the calcined and glucamine modified SBA-15 in adsorption of boron from synthetic solutions and seawater was investigated. Physico-chemical parameters such as adsorbent dose, equilibrium contact time, pH and initial boron concentration were studied in a series of batch adsorption experiments. Boron adsorption on the adsorbent was saturated within 3 h in solution containing 10 mg L-1 of boron, with 5 g L-1 of adsorbent dose. The studies showed that boron were quantitatively removed from water at neutral pH. The glucamine modified SBA-15 possessed higher boron removal capacity, about 45%, than the unmodified SBA-15 which showed only a 23% of boron removal. Thanks to the increase of the adsorption sites due to the grafting. Desorption tests were carried out using 1 M HCl. OMS type SBA-15 was also successfully applied for the removal of boron from seawater in the presence of high concentration of foreigner ions. (C) 2014 Elsevier B.V. All rights reserved.
