The impact of annual bleaching stress on chlorophyll a, energy reserves, calcification, and tissue C and N isotopes was assessed immediately after the second bleaching and after both short and longterm recovery on the reef ( and 11 months, respectively).
STUDIES ON THE ACID ACTIVATION OF BRAZILIAN SMECTITIC CLAYS. Fuller''s earth and acid activated smectitic clays are largely used as bleaching earth for the industrial processing of vegetable, animal and mineral oils and waxes. The paper comments about the .
mins resulted in % CR and %FFA of It was discovered that NaOH activated clay resulted to higher %CR while KOH activated clay shows affinity for reduced %FFA but at higher concentration of 5 M. This research has further established that alkaline activated clays are feasible alternative for acid activated clays in vegetable oil bleaching.
EP Engineered Clays is a global leader in engineered products derived from industrial minerals that include bleaching clays, mineral adsorbent technologies, and catalysis.
Bleaching clays normally contain 10–18% moisture. If the clay is completely dried prior to use, its structure collapses, causing reduction in the bleaching power because of decreased surface area. In addition to these, adsorptive capacity of acid activated clay is reduced if clay is added to hot oil.

Next comes the degree of acid activation and the recognition that one can pursue this beyond the optimum. Third, once the activated clay is washed free of surplus acid, it must be dried to the moisture level at which it operates best. Finally, the activated clay must not be ground so fine that it creates difficulty in filtration after use.
Tonsil® bleaching earth derived from the natural clay mineral bentonite has a purifying effect. It is formed by an acidic activation of bentonite, which changes its special layered structure: the ion exchange with the protons enables additional water to enter between the layers and the mineral swells.
