Efficient degradation of chromium picolinate with simultaneous chromium removal from aqueous solutions using the Fenton process

A novel covalent organic framework for efficient photocatalytic reduction of Cr(vi) and synergistic removal of organic pollutants under visible light irradiation

“…4,5 By contrast with Cr(VI), Cr(III) is less hazardous and is a trace element essential for normal human life activities. 6,7 Consequently, reducing Cr(VI) to Cr(III) has become a hot research topic in the environmental field.…”
