Copper(II) sulfate Wikipedia

Copper(II) sulfate, also known as copper sulphate, are the inorganic compounds with the chemical formula Cu SO 4 (H 2 O) x, where x can range from 0 to 5.The pentahydrate (x = 5) is the most common form. Older names for this compound include blue vitriol, bluestone, vitriol of copper, and Roman vitriol.

Adsorption of Hydrogen Sulfide onto Activated Carbon

To understand the nature of H2S adsorption onto carbon surfaces under dry and anoxic conditions, the effects of carbon pore structure and surface chemistry were studied using activated carbon fibers (ACFs) with different pore structures and surface areas. Surface pretreatments, including oxidation and heat treatment, were conducted before adsorption/desorption tests in a fixed-bed reactor.
