The potential of Parkia speciosa peel (SBP) for removal of procion red mx-5B (PR) through the adsorption process was investigated. PR is a type of azo dye which is toxic to the environment especially in water. Sustainable adsorbents such as agricultural wastes have been promising to reduce the amount of pollution in wastewater due to their accessibility and more economic. The batch study was performed to examine the influence of varies exploratory conditions by fluctuating the dosage, adsorption time, and initial concentration. The main functional groups involved in the dye removal were analysed by Fourier transform infrared spectrometry (FTIR). The isotherm data were examined by the Langmuir, Freundlich and Temkin models. The result showed the equilibrium studies were perfectly associated by the Freundlich isotherm with R2= 0.9993, 0.9786 and 0.9728 for 1, 3 and 5 g of adsorbent dosage that corresponded with pseudo-second-order at a rate constant of 1x10-3/min. The FTIR spectrum of SBP after adsorption showed that changing of the functional groups of PR was presented by the stretch vibration of amine N-H and aromatic C=C, stretching vibrations for azo compound N=N. The remarkable data attained that the stink bean peel can be used as an alternative biosorbent for the removal of organic pollutants including the textile effluent industry. © 2020, AMG Transcend Association.
