Adsorption of Cesium by Expanded Perlite/Ammonium Molybdophosphate Composite

He huaxue yu fangshe huaxue, 2023
Ammonium molybdophosphate(AMP) is a kind of heteropoly salt with strong selectivity and ion exchange capacity for 137Cs. But the small particle size and poor hydromechanical property of AMP, makes it difficult to separate in the later stage.

Microwave Energy for Expanding Perlite Ore

Journal of Applied Research and Technology, 2013
Perlite is an igneous mineral composed by silicon, aluminum, oxygen and water. It can be expanded by heating it upat temperatures above 870 °C, then it becomes plastic, and the steam formed inside pressures out of the mineral.Maximum expansion is possible if the particles are heated up quickly, since the expansion degree strongly dependson the ...
