Coprecipitation is a partitioning process whereby toxic heavy metals precipitate from the aqueous phase even if the equilibrium solubility has not been exceeded. This process occurs when heavy metals are incorporated into the structure of silicon, aluminum, and iron oxides when these latter compounds precipitate out of solution. Iron hydroxide collects more toxic heavy metals (chromium, nickel, arsenic, selenium, cadmium, and thorium) during precipitation than aluminum hydroxide.38 Coprecipitation is considered to effectively remove trace amounts of lead and chromium from solution in injected wastes at New Johnsonville, Tennessee.39 Coprecipitation with carbonate minerals may be an important mechanism for dealing with cobalt, lead, zinc, and cadmium.

Cyanation of 1-Chloronaphthalene in the Presence of Tris(tri-phenylphosphine) nickel. 1-Chloronaphthalene (3.6 grams, 22.3 mmole), Ni[P(C6H5)3]3 (0.75 gram, 0.89 mmole), and ethanol (40 ml) were stirred and warmed up to 60°C. NaCN (1.1 grams, 22.3 mmole) was added, and the mixture was stirred for 3 hrs at 60 °C. The reaction mixture was partitioned between water and diethyl ether. The ether extract contained 1-cyanonaphthalene (3.06 grams, 90% ). The yield was determined by GLC with acetophenone as internal standard. 

The equipment consisted of an electrically heated vertical nickel tube of 2-cm diameter and 45-cm length. This reaction lube had an intermediate partition permeable to gases. A1F3 (30 g, 0.36 mol) was put in the upper half of the tube. The lower half remained empty, and was used to preheat the gas. Gases emerging from the upper end of the tube were cooled to 30 C to cause condensation of the CC14. and then passed through a soda lime tower and finally condensed in a trap cooled with dry ice/acetone. 

Solvent extraction, or liquid—liquid distribution, is the process in which one or more solutes partition selectively between two immiscible liquid phases (Rydbery, Musikas and Choppin 1992). The process is applied industrially in hydrometallurgy e.g., recovery of copper and nickel from ores, in nuclear fuel...
