Bentonite treatment techniques

The refining process most commonly used involves treatment with hot aqueous alkaH to convert free fatty acids to soaps, followed by bleaching, usually with hydrogen peroxide, although sodium chlorite, sodium hypochlorite, and ozone have also been used. Other techniques include distillation, steam stripping, neutralization by alkaH, Hquid thermal diffusion, and the use of active adsorbents, eg, charcoal and bentonite, and solvent fractionation... 

PARAQUAT AND DIQUAT Granular preparations usually contain 2.5% of paraquat md 2.5% of diquafi liquid preparations may contain 20% wA of p aquat only. Treatment consists of reducing p aquat absorption by administering copious noimts of file adsorbents Fuller s Earth or bentonite, with cathartics. Active elimination techniques (forced diuresis, haemodialysis, charcoal haemoperfusion) may also be applied.
