Fe bentonite showed high desulfurization efficiency over Hbentonite. – The highest adsorption of the organic sulfur compounds illustrated at gm of Febentonite and 5 h at 40 C. Under these optimal conditions the modify Febentonite was adsorb about % of sulfur from heavy crude oil, while Hbentonite is low does not be over 40%

kinetics results of Fig. 1 can be used to determine if particle diffusion is the ratelimiting step for phenol adsorption onto bentonite. Weber and Morris (1963) reported that if particle diffusion is involved in the sorption process then a plot of adsorbate uptake versus the square root of time would result in a linear relationship and that particle diffusion would be the

safety of the additive was already evaluated by the Panel in an opinion delivered in 2012. Bentonites are safe for all animal species, the consumers and the environment when used at a maximum level of 20,000 mg/kg complete feed. The results of a new genotoxicity study reinforced the previous conclusion that smectites are nongenotoxic.

In vitro systems demonstrated the ability of bentonite to adsorb aflatoxins in aqueous media at different pH values and to a lower degree in gastric juice. Since in vitro systems do not completely mimic the complex situations during digestion, an efficacy assessment requires a minimum of in vivo data. Two in vivo studies in dairy cows ( 5 g AfB1/kg feed) demonstrated a significant

So HYDROGIM products adsorb these contaminants in paper pulp or loop water very well, avoid agglomeration of these particles and take them out of the process. Thereby, the application of HYDROGIM prevents the formation of deposits all over the paper production process and improves the runnability of the paper machine significantly.

Bentonite (/ ˈ b ɛ n t ə n aɪ t /) is an absorbent swelling clay consisting mostly of montmorillonite which can either be Namontmorillonite or Camontmorillonite. Namontmorillonite has considerably greater swelling capacity than Camontmorillonite. Bentonite usually forms from weathering of volcanic ash in seawater, which converts the volcanic glass present in the ash to

Bentonite content of % has a higher effectiveness than 5% bentonite content in patchouli oil purification [13]. On the addition of 2,5%, bentonite PA content on patchouli oil reached 31% whereas if patchouli oil is added bentonite with %, PA levels only 29%. This means that bentonite is more economical when used as an adsorbent.

The adsorption process was significantly influenced by the solvent type in which phenol was dissolved. The affinity of phenol to bentonite in the presence of cyclohexane was greater than that in water and was lowest in the presence of methanol. Methanol was used to extract phenol from bentonite. The degree of extraction was dependent on the amount of phenol adsorbed

Oils/Food Markets: Bentonite is utilized in the removal of impurities in oils where its adsorptive properties are crucial in the processing of edible oils and fats (Soya/palm/canola oil). In drinks such as beer, wine and mineral water, and in products like sugar or honey, bentonite is used as a clarification agent.
