All-silica beta zeolite is shown to be effective for MTBE removal from water. The silica beta was prepared directly from gel, and it was more effective than dealuminated beta for MTBE adsorption. Water and 2-propanol adsorption isotherms showed that the all-silica beta is more hydrophobic than dealuminated beta. The amount of MTBE adsorbed on all-silica beta increased linearly with MTBE concentration from 9.4 to 590 microg/L.
全硅β沸石被证明对从水中去除甲基叔丁基醚(MTBE)有效。β沸石直接由凝胶制备而成,在MTBE吸附方面比脱铝β沸石更有效。水和2-丙醇的吸附等温线表明,全硅β沸石比脱铝β沸石更疏水。吸附在全硅β沸石上的MTBE量随MTBE浓度从9.4微克/升增加到590微克/升呈线性增加。
