Toxic effect of textile dyes their increasing quantities in air, soil and water environments, because of growing of industrial activities, they must be taken into consideration since they give harm to the environment. We come across textile dyes in natural wetlands as result of uncontrolled industrial wastes. Textile dyes that can accumulate easily in their environments may show toxic effects. Pumice, accruing as a result of volcanic events and durable against chemical factors, is a rock that has porous structure. Pumices have a porous structure because of sudden cooling of the rock and sudden leaving of gases a result of volcanic events. Thanks to these pores, pumices' heat and sound insulation are quite high. The most distinctive feature of pumice from other rocks is that it has different colors and there is not crystal water in its porous structure. Adsorption studies are applied with Van Pumice at pH = 6, the adsorption mechanism and changing dye concentration. As result of these researches, it has been found out that there are different adsorption movements at pH 6 between Neutral Red and Van Pumice. The result of this study shows that the Pumice found in Lake Van gives a better fit for the Langmuir Isotherm (model) and the amount of adsorption increases with the temperature. We thereby conclude that the Pumice located in Lake Van is a recommended adsorbent for filtering the used textile dye in aqueous medium.

“…Conversely the hydrophobicity and ionic property of dyes are influential factor for their complexation with calixarenes. Owing to wider central cavity, calix [6]arenes and calix [8]arenes were proved previously excellent adsorbents for azo dyes relative to calix [4]arenes [22]- [25]. Apart from the size of calix [4]arene cavity, introduction of appropriate functionality in calix [4]arene structures could enhance its complexation ability towards dyes magnificently.…”

2015) Amidoamine calix [4]resorcinarene-based oligomers and polymers as efficient sorbents of azo dyes from water, Supramolecular Chemistry, 27:9, 595-605,The sorption behaviour of three kinds of macrocyclic sorbents -amidoamine tetradodecyloxyphenylencalix [4] resorcinarene 1 and tetramethyloxyphenylencalix[4]-resorcinarene 2; composition of calix[4]resorcinarene 1 1 2, and novel P.1 and P.2 polymers with amidoamine calix[4]resorcinarene units towards three water-soluble azo dyes -methyl orange (MO), acid orange (AO5) and Congo red (CR) was studied. All sorbents form supramolecular complexes with the aforesaid dyes. The best sorbent for MO was shown to be polymer P.1, for the AO5 -composition 1 1 2 and for the CRmacrocycle 2, with high sorption capacities (373, 497 and 625 mg/g, respectively). The main factor in the binding of dyes by all studied sorbents proved to be surface electrostatic interactions. In addition to the Coulomb interactions, the most important factor for the polymers appeared to be the 'net' structure of the polymer with a high concentration of binding sites, providing electrostatic, hydrogen, dipole -dipole and hydrophobic interaction. Hydrophobic substituents in the sorbents exert a significant influence on the dye sorption. The increase of the sorbents' hydrophobicity leads to a lower sorption capacity for MO and CR and a higher sorption capacity for AO5. It was shown that sorption efficiency of the sorbent depends on the 'dye -sorbent' structure conformity.
