ABSTRACT

Filtration is good for separating an insoluble solid from a liquid. (An insoluble substance is one that does not dissolve). Calcium Carbonate, for example, can be separated from a mixture of sand and water using filtration. Talc is a native hydrous magnesium silicate, sometimes containing small proportions of aluminum silicate, purified by boiling powdered talc with hydrochloric acid in water; used in pharmacy as a filter aid, as a dusting powder, and in cosmetic preparations. Gravity filtration uses a polyethylene or glass funnel with a stem and filter paper. Filter paper can have pore sizes ranging from small to large to permit slow to fast filtering. In this research we are going to study the effect of talc in different concentration on filtration rate.
