efficient methods of reactive, acidic and direct dyes in neutral solutions
removing pollutants from wastewater. The by-products from the agricultural and
industrial could be assumed to be low-cost adsorbents. They are abundant in
nature, inexpensive, require little processing, effective materials and ability
to remove cationic dye from aqueous solution. The aim of the present study is
to investigate the removal of congo red dye ions from aqueous solutions using
bioserbents such as pirina, sea food shell and almond shell. The optimum
conditions for adsorption by using a batch method were evaluated by changing
contact time and initial dye concentration. The Langmuir, Freundlich and Temkin
adsorption isotherm equations were derived form the basic empirical equations,
and used for calculation of adsorption parameters. The equilibrium data fit
well the Langmuir, Freundlich and Temkin isotherm. Three simplified models
including Pseudo-Second-Order, Interparticle Diffusion and Elovich were used to
test the adsorption kinetics. These results indicate a significant potential
for the pirina, sea food shell and almond shell as an biosorbent material for
congo red dye removal. </span> </p> <p> </p> </div>}, number={2}, publisher={Erzincan Binali Yıldırım Üniversitesi}
