Wood Waste from Mazandaran Wood and the Paper Industry asa Low Cost Adsorbent for Removal of a Reactive Dye

Mazandaran wood and paper industry (MWPI) generates large amounts of wood waste (WW) daily. The aim of this study is to apply WW from this factory as a low cost and non-conventional adsorbent for reactive blue 19 dye removal from aqueous solutions. For this purpose, effects from main parameters during the adsorption process include contact time, initial pH, adsorbent dose and initial dye concentration. Maximum dye removal efficiency was observed to be 93.79% at a pH of 2 and with 16 g/L of WW. Maximum value of Q for this waste was 30.92 mg-dye/g adsorbent. For the real textile wastewater containing RB 19, the dye removal efficiency was obtained at 73.84%. The adsorption process follows a Langmuir isotherm equation and the pseudo-second order kinetic model.
