The wastes of vine stem and Turkish red pine as an alternative biosorbent for the removal of leather dyes
Journal Title: Proceedings of the International Conference on Advanced Materials and Systems (ICAMS) - Year 2018, Vol 1, Issue
Abstract
The use of high amount water in the industries such as leather, textile and paper causes hazardous wastewater for the environment due to the contents of organic compounds and heavy metals. Discharging high amount of leather dyes such as acid and metal complex to ecosystem pose a problem due to their resistance to biological treatments. Vine stem and Turkish red pine sawdust are agricultural wastes and could be an alternative bio-sorbents for the leather industry due to their cost effectiveness. For this purpose, it was aimed to determine the removal efficiencies of the dyestuff Acid Brown 282 SGR by the use of vine stem and Turkish red pine sawdust. The batch adsorption technique was used for the study and the effect of the pH, biosorbent amount and contact time was investigated. The functional groups of the bio-sorbents were determined by attenuated total reflectance spectra (ATR-IR). The biosorption data showed that Langmuir model was the best fitted model for the sorption of Acid Brown 282 SGR. The maximum adsorption capacities were found as 25.91and 26.67 for vine stem and Turkish pine sawdust respectively. The results revealed that vine stem and Turkish red pine sawdust could be used as low-cost biosorbents for the removal of dyestuff remaining after the dyeing process of leathers.
