Characterization and Adsorption Performance Evaluation of Waste Char
Abstract
Environmental threats such as global warming, soil contamination, ground water pollution and air pollutions are the penalties of the huge generation of wastes from industries and urban areas. Therefore, waste management has become an important issue. An effective waste management includes prevention, reuse, recycling, recovery and disposal of waste. Several technological approaches have been explored to attain any one of the processes. Waste to energy (WTE) conversion is well accepted. Pyrolysis is one such promising technology which can produce three different types of fuel such as, pyro-oil, char and gases from solid or liquid wastes. This pyro char can be used as a good adsorbent. On the other hand industrial effluent contain heavy metals like Lead (Pb), Arsenic (As), and Cadmium (Cd), as well as harmful anions like fluorides, nitrates, and sulphates, which cause extensive damage to our environment.Hence, treatment of industrial effluents is utmost important. In this present study, char material will be prepared from pyrolysis of waste materials and will be used for the liquid phase adsorption of Eosin y. Adsorption isotherm will be evaluated. Characterization of adsorbent will be done. The removal of pollutants from waste water solution using this adsorbent will be presented.
