Diverse material based geopolymer towards heavy metals removal: a review
نویسندگان
چکیده
Metakaolin is a commonly used aluminosilicate material for the synthesis of geopolymer based adsorbent. However, it presents characteristics that restrict its uses such as weak rheological properties brought on by plate-like structure, processing challenges, high water demand and quick hydration reaction. Industrial waste, other hand, contains variety components potential source material. Geopolymer adsorbent synthesized utilizing industrial waste wide range elements offer better ion-exchangeability increase active sites surface geopolymer. limited studies focused heavy metal adsorption in wastewater treatment. Therefore, this paper reviews raw materials This would help development low cost has great adsorption, which could deliver double benefit both management

متن کاملRemoval of heavy metals by ultrafiltration
Large amounts of polluted water are often obtained from the chemical process industry, which require a mandatory treatment before being disposed of. Heavy metals are employed as homogeneous catalyst in numerous processes, so that recovering and/or recycling of those metals to the reaction unit is essential. In this study, ultrafiltration is presented as a useful technique to recover heavy metal...
