Novel Fe₃O₄-poly(methacryloxyethyltrimethyl ammonium chloride) adsorbent for the ultrafast and efficient removal of anionic dyes.

ABSTRACT: The removal of anionic dyes from wastewater has attracted global concern. In this work, a novel Fe₃O₄-poly(methacryloxyethyltrimethyl ammonium chloride) (Fe₃O₄-pDMC) adsorbent for the efficient removal of anionic dyes from wastewater was successfully synthesized by grafting methacryloxyethyltrimethyl ammonium chloride (DMC) on the surfaces of Fe₃O₄. Various characterization analyses confirmed that the obtained Fe₃O₄-pDMC possessed numerous functional groups on its surfaces and retained good magnetic separation properties. Fe₃O₄-pDMC showed ultrafast removal for acid orange 7 (AO7, 58.6%, 1 min) and direct blue 15 (DB15, 98.1%, 1 min), and the maximum adsorption capacity was high (2
