Abstract
Two com. azo dyes were removed from aq. solns. by ad-sorption on a Polish raw halloysite. The dried halloysite samples showed better adsorption efficiency in respect to both dyes than the calcined ones. Sepn. abilities of the azo dyes depended on the preliminary pretreatment of raw halloysite (drying, calcination, milling), size class of the adsorbent fraction used, as well as on the initial concn. of the dye in the soln. The parameters of Langmuir and Fre-undlich adsorption isotherms, as well as of pseudo-first-order and pseudo-second-order kinetic models for the systems were detd.
