2002-5-30The influence of natural organic matter NOM on the adsorption of Al, Fe, Zn, and Pb onto clay minerals was investigated. Adsorption experiments were carried out at pH 5 and pH 7 in the presence and absence of NOM. In general, the presence of NOM decreased the adsorption of metal ions onto the clay particles. Al and Fe were strongly influenced by NOM, whereas Zn and Pb adsorption.Get A Quote
Clay Screening Machines. Clay screening machines are critical to the successful mining of clay for use in the ceramics or construction industry. To create strong products, clay needs to be as pure as possible, although it may be mixed with other materials during the production process. Nevertheless, any impurities in the clay itself could.Get A Quote
