Document type: Language: EnglishCited References: 19Times Cited: 166Times self cited: 22 Article Abstract: The sorption of two dyes, namely, Basic Red 22 and Acid Red 114 onto pith has been studied in terms of pseudo-second-order, pseudo-first-order sorption and intraparticle diffusion processes thus comparing chemical sorption and diffusion sorption processes. The pseudo- second-order model. based on the assumption of a pseudo-second-order mechanism, has been developed to predict the rate constant of sorption, the equilibrium capacity and initial sorption rate as a function of the effect of initial dye concentration, pith particle size, pith dose and temperature.
