Abstract


The accumulation of Cr(VI)will cause mutagenic and carcinogenic effects on humans. Therefore, the standard regulations have been governed by the EPA to control the chromium content in the effluent and drinking water and have made it mandatory [1]. For the better recovery of the adsorbent; Magnetic nano particle based phosphorene titanium nano tubes were used for the first time in action which has been proven to be superior for the Chormium pollutants. MNP-PN-TNT (Magnetic nanoparticle-Phosphorene-Titanium nano tubes)was synthesized from hydrothermal method in this study. The prepared material is used for effective removal of Cr(VI)from the water by adsorption technique in... (More)

MNP-PN-TNT (Magnetic nanoparticle-Phosphorene-Titanium nano tubes)was synthesized from hydrothermal method in this study. The prepared material is used for effective removal of Cr(VI)from the water by adsorption technique in acidic environment. The adsorption capacity was found to be 35 mg g

obtained from RSM (Response Surface Methdology). The adsorption process of MNP-PN-TNT is conformed with a pseudo-second-order kinetic model. Cr(VI)adsorption behavior with MNP-PN-TNT, is spontaneous from the results of thermodynamics analysis. The adsorption mechanism of Cr(VI)with MNP-PN-TNT was evident by O1s, C1s, Cr 2p, Ti 2p, Fe 2p and P 2p of XPS. Cr(VI)is adsorbed with MNP-PN-TNT, in randomness during the adsorption process.
