2020.6.10 After the acid activation, the analysis data showed a significant change in the chemical composition in modified bentonite clay, compared to the raw bentonite clay. The acid activation of bentonite caused an increase in the amount of Si +4 and Ti +4;
Read More2022.1.1 In general, activated bentonite, zeolite 13X, and activated carbon are the three types of adsorbents industrially used in transformer oil purification to date. However, the adsorption behavior and related mechanism of AP removal in the transform oil on the
Read More2015.1.25 The bentonite is a widely available and abundant natural mineral, and can be a low cost adsorbent for water and wastewater treatment. This study reported here was directed towards identifying a cost-effective activation protocol for enhancing
