Abstract

Toxic
effect of textile dyes their increasing quantities in air, soil and
water environments, because of growing of industrial actives, they
must be taken into consideration since they harm to environment. We
come across textile dyes in natural wetlands as result of
uncontrolled industrial wasted. Textile dyes that can accumulate
easily in their environments may show toxic effects.

Pumice,
accruing as 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 metal concentration. As result of these
researches, it has been found that there are different adsorption
movements at pH 6 between textile dyes 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.

It
is thereby concluded that the Pumice located in Lake Van is a
recommended adsorbent for filtering the used textile dye in aqueous
medium.
