AI Article Synopsis
- A novel material was created from oil shale using a chemical activation process involving sulfuric and nitric acids.
- The resulting product exhibits unique properties, combining the benefits of activated carbon and zeolite, and features a variety of crystalline structures including zeolite Y and Na-X types.
- The material demonstrates significant sorption ability, effectively removing chromium with a capacity of 92 mg/g, while also displaying functional groups on its surface for enhanced reactivity.
Article Abstract
A novel activated carbo-aluminosilicate material was prepared from oil shale by chemical activation. The chemicals used in the activation process were 95 wt% sulfuric and 5 wt% nitric acids. The produced material combines the sorption properties and the mechanical strength of both activated carbon and zeolite. An X-ray diffraction analysis shows the formation of zeolite Y, Na-X, and A-types, sodalite, sodium silicate, mullite, and cancrinite. FT-IR spectrum shows the presence of carboxylic, phenolic, and lactonic groups on the surface of this material. The zero point of charge estimated at different mass to solution ratio ranged from 7.9 to 8.3. Chromium removal by this material showed sorption capacity of 92 mg/g.
