In this study, the use of low-cost, widely available waste biomass of sour cherry stone (CS) was
used for the production of biochar (CSB), and used as an alternative to the expensive removal
techniques for removing toxic dye Brilliant green (BG) from wastewater. Produced CSB was
characterized using Fourier Transform Infrared spectroscopy with attenuated total reflectance
(FTIR-ATR) and Thermogravimetric method (TG-DTG). FTIR-ATR results indicated the
evolution of aromatic functional groups replacing aliphatic groups of CS. The effects of various
operational parameters (pH, contact time, initial dye concentration, adsorbent dosage and
temperature) were investigated and optimal conditions were determined. According to the results,
optimized parameters were: pH 6, contact time of 120 min, initial dye concentration of 50 mg/L,
adsorbent dosage of 2 g/L, and temperature of 35 ℃. These parameters were used for kinetic and
isothermal investigations. The adsorption of BG was evaluate...d using two kinetic reaction models
(pseudo-first-order and pseudo-second-order). The results showed that the pseudo-second-order
model fitted better the experimental data, indicating chemisorption involving valence forces
through the exchange of electrons between the dye and CSB. According to the adsorption isotherm
analysis, the Langmuir isotherm model better fits experimental data than the Freundlich and Sips
models. The maximum monolayer adsorption capacity of BG on CSB was found to be 109.25
mg/g. The RL value (0.392) verifies that the BG adsorption on CBS is a feasible process. Using
CS as a raw material for biochar production, the problem of waste disposal, its decomposition and
secondary pollution might be solved. In the same time, this waste materials would gain not only
ecological but also significant economic value. These findings demonstrated that CSB, which is
made from waste biomass, can be used as a promising and affordable adsorbent for removing dyes
from aqueous solution.
