STUDY ON CHARACTERISATION FOR THE REMOVAL OF CRYSTAL VIOLET DYE FROM INDUSTRIAL WASTEWATER USING SPATHODEA CAMPANULATA LEAVES--SEM, FTIR, XRD ANALYSES.

The objective of the present study is to remove crystal violet (CV) dye from their industrial waste water using Spathodea campanulata leaves powder as low cost biosorbent in a batch study. The effects of parameters were contact time, solution pH, initial CV dye concentration, biosorbent dosage, average particle size of the biosorbent and temperature. Scanning electron microscope (SEM) analysis is used to investigate the surface morphology of the biosorbent. The morphological characterization of the Spathodea Campanulata leaves biosorbent before and after biosorption of crystal violet was studied. The Fourier transform infrared spectroscopy (FTIR) provides structural and compositional information on the functional groups present in the biosorbent. The functional groups present in the Spathodea Campanulata leaves biosorbent before and after biosorption of crystal violet was investigated within the range of 400 – 4000cm-1 wave number. The analysis of Fourier transform infrared spectrum shows the presence of large number of functional groups present on the surface of the Spathodea Campanulata leaves biosorbent. XRD patterns for crystal violet treated powder exhibit more amorphous nature and increase in surface area and porosity. The maximum removal efficiency was predicted to be 89% for crystal violet, which was obtained at a temperature of 303.28 K, solution pH of 6.06, initial dye concentration of 20.09 mg/L and biosorbent dosage of 1.50g, on to spathodea campanulata leaves.
