Development of Novel Waste Biomass-Based Sorbing Film for Smog Removal

Abstract

Biochar is a powerful adsorbent for contaminants present in polluted water, soil, and gases. The adsorption capacity of biochar depends upon feedstock biomass and pyrolytic conditions. In this study, three types of biomass were collected and converted into biochar employing pyrolysis. Each biochar sample was tested individually for adsorption of smoke in simulated conditions. Activated charcoal (a known adsorbent) was used as control. The time taken for clearance of smoke by individual biochar sample was 23 minutes, while without biochar, it was 35-40 minutes gave heat treatment to one of the biochar samples, and smoke by the heat-treated sample in simulated condition was adsorbed in 15 minutes. FTIR analysis of one of the samples revealed prominent peaks, bending, and stretching in different ranges of different samples. The results indicated that biochar from all three biomass is effective in the adsorption of smoke. Heat-treated biochar exhibited higher adsorption capacity as compared to crude biochar.
