Abstract
In the present investigation, the adsorption potential of Okara for methyl orange from a dye solution was explored. The effects of pH, adsorbent dosage, and agitation time were studied in batch experiments. Results showed higher adsorption of methyl orange on Okara in the range of pH 2 to 7, and the maximum adsorption was obtained at pH 3. Moreover, adsorption of methyl orange increased with increasing Okara dosage, and constant adsorption was observed at dosages of 1.0g and higher. Additionally, adsorption of methyl orange on Okara occurred rapidly in the early period, and 85% of the methyl orange was adsorbed in 1 min of agitation time. Our results showed that Okara is a rapid and effective adsorbent of methyl orange.
