Abstract: In this study, kenaf core fibre KCF with size 0.25–1 mm, was successfully by treating with (CHMAC) as quaternization agent. The MKCF was characterised by Brunauer, Emmett and Teller (BET) analysis, Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscope (SEM), with pH = 6.5 and constant shaking rate of 150 rpm. Was developed to stimulate the adsorption of AR114 by MKCF under varying parameters such as pH, dosage, dye concentration and speed. In addition, isotherms and kinetics adsorption studies were estimated for determination of the equilibrium adsorption capacity and reactions dynamics; respectively on adsorption by modified kenaf core fibre was investigated. Results showed that the best dosage of MKCF was 0.1 g/100 mL, the maximum removal of AR114 Was 99.14 at 300C. The results also showed that the equilibrium data were represented by Freundlich isotherm with correlation coefficients R2= 0.8395 and the kinetic study followed the pseudo-second-order kinetic model with correlation coefficients R2= 0.9953 mg/L. Furthermore, the maximum adsorption capacity 238.1 mg/g. Adsorption through kenaf was found to be very effective for the removal of the Acid dyes.
