Abstract
Removal of malachite green (MG) onto fir (Abies nordmanniana) cones biomass (FCB) as a lingo-cellulosic-based structure material was investigated in the present study. Characterization of FCB was performed using Fourier transform infra red and scanning electron microscobe analyses. Several parameters (biomass dose and particle size, dye concentration, temperature, and pH) were investigated to determine optimal working conditions. Subsequently, FCB yelded a qe of 2.2 mg/g for 50 g/L FCB, in an MG solution of 110 mg/L, pH 3.3, at a temperature of 21 °C, on a 0.2-0.4 mm fraction powder after 146 h of contact. Adaptive neuro-fuzzy interference system modeling was applied to experimental data and results showed that predicted model fitted experimental data with R2 = 0.994. In a nutshell, it can be concluded that FCB shows good potential for treating MG contaminated waters.
