Iodine is a crucial element in various industries, but it is one of the least abundant nonmetallic elements on Earth.

Organic solvents with densities greater than and less than that of the aqueous solution are used to extract the iodine. The aqueous solution of food color is blue. Iodine in water is yellow, and when ...

The technique of extraction is used to separate an aqueous solution of copper (II) chloride and iodine. Organic solvents with densities greater than and less than that of the aqueous solution are used ...

Soaking up pollutants like a sponge, porous organic polymers (POPs) may be the key to reducing greenhouse gas emissions, according to researchers.
