Bentonite is widely used in industrial wastewater treatment due to its large reserves and excellent physicochemical properties. In order to further improve the properties of bentonite, natural bentonite needs to be modified before application. The common modification methods of bentonite include thermal activation, acid activation, …

Suspension of bentonite in water leads to the swelling of bentonite platelets due to the ingress of water molecules. PSD was determined after aging for 24 hours to allow the full hydration of 6 wt.% wet-sieved bentonite (WSS-Bentonite) both before chemical treatment (i.e., Ca-bentonite) and after Na 2 CO 3 activation

Abstract The acid activation of bentonite from Middle Anatolia, consisting of mostly montmorillonite, with a hot solution of H2SO4 with different concentrations was carried out. SEM images, nitrogen sorption isotherms and FTIR spectra were used to examine structural changes of the bentonite with acid activation. Acid–base titration …

Remove the top 4 to 6 inches of the soil from the pond bottom. Next, you should fill any deep holes or crevices with a uniform mixture of one part bentonite to five parts soil. Then smooth the area by roller or drag. Cover the area with the prescribed amount of sodium bentonite. It is very important that the bentonite layer is even and that ...

A simple physical method composed of grinding, dispersion and centrifugation was adopted to purify a low-grade bentonite from Zhejiang, China. This experiment increased the montmorillonite content of the bentonite from 44% to 96.5% with montmorillonite yield over 70%. The influence of the grinding time of raw bentonite, the …
