  The use of orange peel as low-cost and eco-friendly adsorbents has been investigated as an ideal alternative to the current expensive methods of removing dyes from wastewater. This paper concerns with the removal of Blue 56 from aqueous solutions by orange peel. The effects of pH, initial concentration, adsorbent dosage, and particle size of adsorbent, temperature and also isotherm data analysis and adsorption kinetics were investigated. A maximum removal of 96.76% was obtained at pH 2.5 for an adsorbent dose of 0.2 mg. Rate of adsorption was found to conform to pseudo-second-order kinetics with a good correlation (R2=0.99). The maximumadsorption capacity obtained from Langmuir equation was9.69 (mgg-1). پرونده مقاله

  In the present investigation, shells of pistachio are used as adsorbents and they have been successfully used for the removal of Blue 56, from water samples. The effect of various parameters such as: pH, amounts of adsorbents, size of adsorbent particles and contact time on removal processing were investigated. Inthisstudy Freundlichabsorptionisotherms and Langmuir were investigated. The experimental data were correlated reasonably well by the Freundlich adsorption isotherm and isotherm parameters were calculated. In order to investigate the efficiency of Blue 56 adsorption on the pistachio shell, pseudo-first-order, pseudo-second-order, Elovich and intra-particle diffusion kinetic models were studied. Themodel that hadgoodcorrelationtoattractFreundlichwas chosenasthemodel. Its kineticsfollowsthepseudosecond order reaction. پرونده مقاله
