Preparation of Activated Bio-char from Corn Stalk for Color Treatment of Effluent from Packaging Paper Mill

In recent years, the paper industry is developing strongly and plays an important role in the industry of our country. Most of the factories have their own wastewater treatment systems. In general, wastewater in paper mill is very difficult to treat and to handle, especially color (Pt–Co) index. In...

Description
Summary:In recent years, the paper industry is developing strongly and plays an important role in the industry of our country. Most of the factories have their own wastewater treatment systems. In general, wastewater in paper mill is very difficult to treat and to handle, especially color (Pt–Co) index. In this research, activated carbon with a high surface area and high adsorption capacity was prepared from corn stalks, an agricultural by-products. The suitable conditions of pyrolysis were investigated to prepare activated bio-char from corn stalk. Then, as-obtained carbon material was applied for color treatment of effluent from paper mill. The activated carbon showed high efficiency and capability in color removal of waste water, with the color reduction of 77%.
