Conversion of Cr(VI) to Cr(III) in Water Using Amino-Modified Ordered Mesoporous Silicas: Influence of the Functional Group Architecture

Two nitrogen-modified mesoporous MCM-41-type silicas were synthesized by the sol–gel route and post-grafting surface modification procedure, obtaining an aminopropyl-modified MCM-41 (denoted MCM-41-N) and an aminoethyl-aminopropyl-modified MCM-41 (denoted MCM-41-NN). Hexavalent chromium removal from...
