Abstract:

The paper presents a preliminary study of chemisorption onto anionic and cationic clays, in order to reduce the content of pollutants from a paper printing effluent, collected after technological step named: printing of paper fabric manufacturing. The procedure of filtration fallowed by adsorption process is an effective, fast and low cost technique for treatment of black effluent resulting from paper printing industry. The key parameters tested to achieve a high efficiency for the movement of micropollutants from printing fluid were substrate dose and contact time. The highest treatment performance was obtained for cationic substrate at pH = 6.80, in contact and agitated magnetically for 30 respectively 90 minutes at room temperature.

Keywords:

anionic and cationic clays, chemisorption, paper printing industry, wastewaters.
