Kaolin was artificially contaminated with the POPs of target concentrations. Because of the low solubility of POPs in water, hexane was used as solvent to dissolve completely the POPs required to yield the target concentrations 355. Kaolin was soaked with these solutions at the ratio of approximately 500 mL solution per 1 kg kaolin. Then, the mixtures were stirred well to make

Types of Chemical Weathering Reactions. Hydrolysis - H or OH-replaces an ion in the mineral. Example Leaching - ions are removed by dissolution into water. In the example above we say that the K ion was leached. Oxidation - Since free oxygen (O 2) is more common near the Earths surface, it may react with minerals to change the oxidation state of an ion.
The simplest means of caring for granite is cleaning. Clean stone surfaces with a neutral cleaner, stone soap, or mild dishwashing detergent and warm water. Too much cleaner or soap may leave a film.

Environmental characteristics include the nature and distribution of inorganic contaminants, such as metals and metalloids like arsenic, iron, and lead, in clay-bearing rocks. These environmental factors have the potential to affect the use of clays in natural and industrial applications. -
Paper - Kaolin is the most extensively used additive in the manufacturing of paper, primarily as a filler and coating.Kaolin is combined with wood pulp or fiber to generate substantially more paper filler, and thus more paper. It is a less expensive alternative to all wood paper filler, which has become more expensive as demand for paper increases and supply of wood decreases.
