In this study, the effects of size of adsorbent, temperature, pH of solution, ionic strength, presence of inorganic substances such as calcium ion, magnesium, ions, chloride ions, fertilizers and presence of organic substances such as dissolved organic matter, surfactant, other herbicides on sorption of 2,4-D and atrazine onto rubber granules were investigated. The removal efficiency was more for fine adsorbent particles. Temperature played an important role in sorption process. Temperature effect was endothermic for 2,4-D and exothermic for atrazine, respectively. The removals were maximum at pH 4 for 2,4-D and at pH 6 for atrazine. The presence of other herbicide (butachlor) reduced sorption capacity of rubber granules by similar to 10% for both 2,4-D and atrazine. All other factors had insignificant effect on sorption capacity. The mathematical expressions were developed for predicting the overall percentage removal of 2,4-D and atrazine on the basis of major four controlling factors viz. adsorbent size, temperature, pH and presence of other herbicide.
