Treatment of Fluorine Water by Porous Analcite Balls

Analcite minerals were found from sedimentary rocks of cretaceous system in Ordos basin using micro-analysis. Porous analcite balls were prepared by analcite rocks after purifying and modification. Then porous analcite balls were used in treatment of fluorine water. Treating 100 mL solution containing 5. 00 mol/L fluorine, good result was obtained when the experimental condition of analcite balls was : dosage 3. 0 grams, stilling 48 hours after stirring, diameter 3 millimeters. The absorption equation of porous analcite balls is in conformity with the Langmuir equation. The rate equation of porous analcite balls is in conformity with the Banerm equation. Consumed analcite balls almost recovered activity after regeneration. The efficiency of fluoride removal is slightly lower when porous analcite balls have been regenerated for many times.
