“…Sorption capacity for any organic pollutant is believed to depend upon three main factors namely (a) the sorbate characteristics like polarity, hydrophobicity, molecular size, aqueous solubility, functional groups present and branching, (b) the solution of the system like pH, temperature, ionic strength and (c) the sorbent characteristics like surface area, organic matter, mineral surfaces, pore size, etc., (Belfort, 1979). In the present study, when comparison of solubility of the pollutants studied with K p values was done (Table 1), it was observed that decrease in solubility brought about an increase in K p values.…”
