- This study investigates As, Ni, Zn, Cd, and Pb removal onto limestone, starfish, black shale, and concrete from
wastewater. Natural materials or waste products with a high capacity for heavy metals can be obtained and employed
of with little cost. For investigating the neutralization capacity, the change in pH, Eh, and EC as a function
of time was quantified. Of the adsorbing agents, concrete showed that the high neutralization efficiency for AMD
and maintained the pH value above 11. The adsorption of heavy metals by the samples was influenced by compositions
of adsorbing agents. The experimental results of desorption revealed that when the adsorption or precipitation
occurs, there was no significant releasing from all adsorbing agents. In this study, the results suggest that concrete
can be used successfully in the treatment of acid mine drainages with mixed metal-contaminated wastes.
