The acid treated coconut coir exhibited better adsorption capacity in cationic dye MB than anionic dye AO7 and the data obtained can be well described by both Langmuir and Freundlich isotherm models. According to the Langmuir isotherm model, the maximum adsorption capacities of MB and AO7 onto acid treated coconut coir were 121 mg/g and 10 mg/g, respectively. The adsorption behavior of MB and AO7 onto acid treated coconut coir was analyzed with first-order Lagergren model and pseudo-second order model. 2014-05-29T06:52:10Z 2014-05-29T06:52:10Z 2013-09 Article Separation Science and Technology (Philadelphia), vol. 48(14), 2013, pages 2125-2131 0149-6395 http://www.tandfonline.com/doi/abs/10.1080/01496395.2013.792839#.U4a9yXKSyyo http://dspace.unimap.edu.my:80/dspace/handle/123456789/34860 en Taylor and Francis Group, LLC.
