Continuous removal of Cr(VI) and Orange II over a novel Fe0-NaA zeolite membrane catalyst
Separation and Purification Technology(2019)
摘要
A novel paper-like sintered stainless steel fibers supported Fe0-NaA zeolite membrane catalyst was prepared for continuous removal of Cr(VI) and Orange II (OII) in a fixed bed reactor. The Cr(VI) was reduced efficiently by using the catalysts with large voidage. Followed the OII was degraded based on the production of hydroxyl radicals with high reactivity using ferrous ions as catalysts, which resulted from the oxidation of Fe0 on the NaA zeolite membrane/PSSFs.
