Synthesis and characterization of novel friendly biosorbents and it uses for removal of crystal violet dye from wastewater

The methodology of this work preparing of low cost and environmental friendliness biosorbents and used for the treatment of industrial wastewater by removing dyes from its effluent. The cellulose and lignin biosorbents were getting from the camphor tree using acidic and alkaline treatments. There are characterized using ultraviolet, visible and infrared spectra surfaces functional groups and pH zero point charge. The cellulose and lignin biosorbents were applied for removing of crystal violet from wastewater. The effect of intial pH solutions, shacking time, crystal violet concentration, and solution temperature on the removal of dye were test The cellulose and lignin biosorbents has a high efficiency for completely removing (95–100%) of Cr.V at pH 5-7 within a period from 2 to 5 min. The pseudo-second-order model was best described by kinetics process with R2 values (1.0). The negative values of ΔG (-3.1 and -9.2 kJ/mol) for removing of Cr.V using cellulose and lignin biosorbents showed that the feasibility of the removing process and its spontaneous nature. The lower relative standard deviation (RSD% 1.32-3.39) for five replicating procedures (n=5).
