Biosorption of Metal complex Orange R dye by custard apple bark (Annona squamosa) in aqueous solu... more Biosorption of Metal complex Orange R dye by custard apple bark (Annona squamosa) in aqueous solution and textile industry wastewater was investigated. Batch experiments were carried out to determine the effect of pH, particle size, biosorbent dose, contact time and initial dye concentration. Characterization of biosorbent was also done by FTIR and SEM. Biosorption isotherm models were also applied to experimental data. The results showed that the data fitted well for Langmuir isotherm model as well as Fruendlich isotherm. The study proves the effectiveness of Annona squamosa bark for the removal of metal complex dyes from the wastewater.

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 stud...
