dc.description.abstractThe aim of this study was to develop a low-cost method for effective removal of Cr(VI) ions from wastewater, but also to valuate this residual of major industry for its adsorption capacity. Therefore, the residual lignin produced from paper industry was utilised as an adsorption material and the effects of lignin amount used, pH of solution and contact time on removal capacity of chromium from wastewater were investigated. Analysis of Cr(VI) ions was performed with both spectrometric and volumetric standard methods. The results obtained from both methods were in good agreement with 2 % relative error. Ninety-three % of Cr(VI) ions were adsorbed by 0.5 g residual lignin at pH 3 and 7 hours contact time. This result underlines that residual lignin could be used as a low-cost adsorbent material to remove Cr(VI) ions discharged into the environment with wastewaters.
