摘要

The industrial effluents containing volatile organic compounds manipulate the purity of the environment. Dichloromethane emerges as the toxic malodor that causes carcinogenicity, mutagenicity and teratogenicity. The aim of the present study was to find out the potency of hybrid materials for the removal of dichloromethane using raw rice husk, coconut shell, metal organic framework and Pseudomonas aeruginosa. The identification of bacteria was done by biochemical methods and 16SrRNA test. The characterization of adsorbents was done using sophisticated fourier transform infrared, field emission scanning electron microscopy and x-ray diffraction technique. The particle size of adsorbents was calculated using the Scherrer equation. The analysis of the final concentration of dichloromethane in hybrid materials was done by gas chromatography-flame ionization detector. The removal percentage obtained using Pse + RRH, Pse + CSAC, Pse + MOF (UiO-66(Zr), Pse + RRH + CSAC, Pse + RRH + CSAC + MOF (UiO-66)(Zr) was 96.87%, 99.80%, 97.63%, 97.35%, 98.08%, respectively with 50 mg/L of dichloromethane concentration. On the other hand, the removal percentage obtained using Pse + RRH, Pse + CSAC, Pse + MOF (UiO-66(Zr), Pse + RRH + CSAC, Pse + RRH + CSAC + MOF (UiO-66)(Zr) was 96.5%, 99.5,% 96.5%, 97.0%, 98.09, with 200 mg/L of dichloromethane concentration. The removal percentage obtained using alone Pseudomonas aeruginosa with 50 mg/L and 200 mg/L of dichloromethane was 93.78% and 92.33% respectively. The maximum removal percentage was achieved by a hybrid material using Pseudomonas aeruginosa and coconut shell.
