Usage of the low-cost sorbent for the removal of 3,5-dichlorophenol from the wastewater was investigated. Industrial solid waste (red mud) was selected as a low-cost sorbent. The effects of adsorbent dose, contact time, and temperature on sorption process were monitored. The initial concentration of the monitored pollutant was 4 mmol.L-1. The results show that the mass of the adsorbent and the contact time with the sorbate has a relatively high impact on the sorption process. However, the temperature affects the sorption at a lower level. The highest efficiency of sorption 95.62% was achieved by the red mud (amount 2.5 g) after 48 hours contact with 3,5-dichlorophenol at 25 °C. At the temperature of 50 °C (amount of red mud 2.0 g) the efficiency after 48 hours was 92.77%. Relatively high sorption efficiency of the test material makes it preferable and very attractive for the use as an alternative sorption material. [ABSTRACT FROM AUTHOR]
