摘要
The present invention can simultaneously remove not only cationic heavy metals such as lead, copper, and cadmium from wastewater discharged from the chemical industry, but also anionic heavy metals such as hexavalent chromium, and has excellent reactivity to cationic heavy metals, but hexavalent Nano-zero ironickel binary metal-supported zeolite that improves the properties of zeolites with low reactivity to contaminants such as chromium and that the reduction efficiency gradually decreases due to rapid surface oxidation of nano-zero iron. It relates to an adsorbent and a method of manufacturing the same. On the other hand, the zeolite adsorbent is a recycled fly ash that is conventionally buried as industrial waste, and can simultaneously remove heavy metal cations and heavy metal anions in water, and has excellent adsorption efficiency, thus securing economical efficiency through resource recycling and preventing environmental pollution. It has an excellent effect.
