“Various pollutants like dyes and chemicals that mix easily with water come from factories. These must be treated thoroughly before they can be released into the environment, but existing systems using iron as a base material are not effective and can only be used once,” KIST pointed out.

The researchers checked other materials and discovered that nickel sulfide has excellent properties in dealing with polluted water.

“Nickel itself is common and cheap, and since the new catalyst can be used several times, this treatment system is significantly more economical to employ,” the institute said.
