| Abstract | ||
| single and binary competitive sorption of phenol and p-nitrophenol onto clay modified with quaternary ammonium (Hexadecyltrimethyl ammonium) was investigated to obtain the adsorption isotherms constants for each solutes. The modified clay was prepared from blending of local bentonite with quaternary ammonium. The organoclay was characterized by cation exchange capacity. and surface area. The results show that paranitrophenol is being adsorbed faster than phenol. The experimental data for each solute was fitted well with the Freundlich isotherm model for single solute and with the combination of Freundlich- Langmuier model for binary system. | ||
