An investigation has been made to study clay as sorbent in the treatment of the hazardous contaminants of potential sludge leachate emanating from industrial landfills.
Experimentally was studied six highly toxic and hazardous chemicals, which include: phenol, aniline, cyclohexanol, cyclohexanone, cresol and monochlorophenol. Vermiculate, Kaolinite, Attacote and Hectorite clays were studied as the sorbent material. Removal of organic pollutants were measured using a total organic carbon analyzer (TOC).
Results indicate that these clays can be used for some treatment of the above mentioned organic compounds. The study shows that removal of organic pollutants by clay depends on several factors, such as pH characteristics, washing procedures, residual carbon content of the clay, polarity and solubility of the compounds, and contact time.
In demonstrating utilization of clay material to treat organic pollutants, this study has indicated a treatment technology which may have some potential.
