Evaluation of sterilization possibility in water environment of activated nano MnO2 coated on calcined laterite

Tóm tắt Evaluation of sterilization possibility in water environment of activated nano MnO2 coated on calcined laterite: ... removal on its own, but it can be utilized as an appropriate carrier material. On the other hand, nanoparticles MnO2 have a large surface area and high oxidation potential which make them excellent candidates for the bacterial removal in general. 2.

Before coating, the surface of laterite was quite smooth; but after coating there were nanoparticles of MnO2 in barbed sphere shape distributed tight all over laterite surface.
