Sorption characteristics of heavy metal ions by a natural zeolite

Abstract: Zn2+ > Ni 2+ , related to the first hydrolysis equilibrium constant. The metal removal efficacy was strongly dependent on pH, and to a lesser extent on metal/zeolite ratio.

“…The statistical data have shown a fair goodness of correlation for pseudo-second-order kinetics (Fig. 5), which were reported previously for heavy metal adsorption by other low-cost adsorbents, such as peat and zeolite for the indication for a potential application in column water treatment [6,16]. After the application of the pseudo-second-order kinetics model, the results were listed in Table 4.…”

“…More effective purification systems, such as ion-exchange columns, are often more expensive and, hence, unsuitable for large-scale application [1] . For these reasons, many researchers studied the behavior of natural organic or inorganic materials which have high sorption capacity and are particularly abundant and inexpensive for the removal of heavy metals from various effluents [2][3][4][5][6] . Some of these low-cost materials include peat, bark, lignin, agricultural wastes, fly ash, and clay minerals [7] .…”

“…Застосування інтоксикованим щурам сорбентів та порівняння отриманих резуль-татів вказує на їх позитивну коригувальну ефективність, особливо при застосуванні клиноптилоліту і морденту [12][13][14][15]. У нашо-му дослідженні спостерігалась нормалізація практично всіх досліджуваних біохімічних показників сироватки крові до таких значень, як у інтактних тварин.…”
