Comparative biosorption of acid red yg dye from aqueous solution and textile industry wastewater using syzygium cumini seeds and borassus flabellifer seeds peels

Application of Syzygium cumini seeds and BorassusFlabellifer Seeds Peels as biosorbents for removal of Acid Red YG dye from aqueous solution and textile industry wastewater were investigated. Batch experiments were carried out to determine the effect of pH, particle size, biosorbent dose, contact time and initial dye concentration and even characterization like FTIR and SEM along with desorption studies were also carried out. Maximum dye biosorption was achieved at pH 2.0 for Syzyguim cumini seeds (92.60 ) whereas biosorption for Borossus flabellifer seeds peels (86.04 ) was achieved at pH 3.0, particle size 212µm for both, biosorbent dose of 0.8 g/L for Syzygium cumini seeds and 1g/L for Borassus flabellifer seeds peels, contact time remained the same as 60 min and initial concentration of 50mg/L. The pseudo-second order and equilibrium biosorption data fitted well to Langmuir than Freundlich isotherm models for both the biosorbents. The biosorption results in this study indicated that the seeds of Syzygium cumini and seeds peels of Borossus flabellifer are attractive alternatives for removing acidic dyes from wastewater
