| dc.description.abstract | Biochar is widely studied and applied for its beneficial effects in different fields. It has prominent characteristics to behave as efficient and cost-effective sorbent. This study investigates surface properties, porosity and adsorption properties of biochar and determine its applicability for removal of toxic pharmaceutical pollutant Tetracycline from waste streams. Four samples of biochar provided by Sintef Energy were characterized by XRD, BET, TGA and its adsorption characteristics using UV spectroscopy and adsorption isotherm. The effect of different parameters on adsorption uptake was also studied and performed by varying pH of the solution. It was observed for biochar samples having chips form possess smaller pore size and larger overall pore volume. The biochar samples prepared under CO2 atmosphere possess larger surface area. The biochar samples however seem to carry comparable properties. The adsorption isotherm indicates increase in adsorption capacity of biochar by increase in pH value of the solution. The adsorption was analyzed at 24hr, 72, 96 and 120 hours of interaction. The results from this study may facilitate investigations for removal of toxic pharmaceutical contaminants from water bodies and waste streams and optimizing removal process of such compounds. | |
