In-situ Growth of Nb2O5 Nanorods on Diatomite and Highly Effective Removal of Cr(VI)

doi:10.15541/jim20170308

Abstract

Abstract:

Nb₂O₅ nanorods decorated diatomite were synthesized via a hydrothermal method by using niobic acid, ammonium oxalate and sodium dodecyl benzene sulfonate (SDBS). The as-prepared samples were characterized by SEM, TEM, XRD, BET, and FT-IR techniques. The Nb₂O₅nanorod was obtained with length of 500~700 nm and diameter of 25~35 nm. BET test showed that specific surface area of Nb₂O₅ nanorods decorated diatomite reached 157 m²/g which show a high adsorbance tendence. Under visible light irradiation, the adsorption capacity for Cr (VI) could be 220 mg/g. With the assistance of UV-light photoreduction, the maximum removal capacity for Cr (VI) could be 340 mg/g, and the absorbed Cr(VI) was transformed to Cr(III). After photodegradation for five times, the degradation rate of Cr(VI) (100 mg/L) were still at about 93%. Nb₂O₅ nanorods/diatomite could adsorb Cr(VI) from sewage effectively and in the meantime accomplish the toxicity degradation, showing a promising treatment of Cr(VI) containing waste water.

Key words: diatomite, Nb₂O₅nanorod, Cr(VI), adsorption, toxicity degradation
