Abstract

Proučavana je provodljivost vodenih suspenzija bentonita. Polazni Ca-bentonit (Ca-Mont) je jonskom izmenom u jonoizmenjivačkoj koloni preveden u Na-oblik, a zatim su iz Na-bentonita (Na-Mont) sintetitisani organobentoniti-Do-Mont (100-Na), Pr-Mont (50-Na) i Pr-Mont (100-Na). Odredivana je provodljivost polaznog, Na-Mont i organobentonita, pri različitim koncentracijama vodenih suspenzija (5-20 mas%). Najveća vrednost provodljivosti je dobijena za 20% suspenziju Na-Mont, dok organski katjon u strukturi bentonita smanjuje njegovu provodljivost.

The electrolytic conductivity of bentonite aqueous suspensions was investigated. The starting material (Ca-Mont) was exchanged with sodium ions, using an ion exchange column. The sodium form of bentonite (Na-Mont) was used to obtain organobentonites. The electrolytic conductivity of the starting material, Na-Mont and organobentonites was studied for different suspension concentration. The highest value of the electrolytic conductivity was obtained for Na-Mont, while the organic cation in the bentonite structure decreased the electrolytic conductivity.
