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.
