W1 (TM) is an acid activated bentonite clay adsorbent specific for the removal of chlorophyll, heavy metals, and fats. W1 is very effective at bleaching and refining while preserving the terpenes present in the oil. Unlike other clays, the ability to remove soaps and free fatty acids which are produced during the bleaching process reduces the amount of clay needed to bleach.

Abstract—The useof unactivated bentonite, and unactivated bentonite blended with limestone for the treatment of acid mine drainage (AMD) was investigated. Batch experiments were conducted in a 5 L PVC reactor. Unactivated bentonite on its own did not effectively neutralize and remove heavy metals from AMD. The final pH obtained was below 4 and the metal removal efficiency was below 50% ...
Acidactivated bentonite (CAS #) of the present petition is composed of odorless, virtually dustless, free flowing granular particles. Typically, the product has a density of 5055 lbs/ft3, pH (5% slurry in DI water), granular mesh size (16/48 mesh). Once formed, the probability of environmental contamination is quite low. If spilled, it can simply be swept up and reused. If ...

bentonite from a technological and economical point view. The results showed that Saudi bentonite is suitable for acid activation. Furthermore, it was proven that Saudi activated bentonite is suitable for bleaching unbleached refined corn oil [18, 19]. Saudi activated bentonite was used for the removal of lead and nickel from aqueous solutions. The results showed that using Saudi bentonite to ...
through ion exchange and acid activation,it is possible to attain some similar properties for the two types of clay: Calcium bentonite can be processed to achieve properties that may permit it to obtain market share in some traditional sodium bentonite appliions. Research to modify process technology for bentonite should be focussed on the development of montmorillonite with uniform ...
The acid activation of bentonite from Middle Anatolia, consisting of mostly montmorillonite, with a hot solution of H 2 SO 4 with different concentrations was carried out. SEM images, nitrogen sorption isotherms and FTIR spectra were used to examine the structural changes of the bentonite with acid activation. Acidbase titration method was applied to determine the surface acidities. The ...
