Development of nanostructured environmental material for water treatment

Arsenic is a toxic substance which occurs in groundwater occurs mostly as arsenite As(III) or arsenate As(V). Arsenic is more toxic in the +3 than in the +5 state and that many countries in the world consist of aquifers with arsenic concentration at unhealthy concentration. However, most conventiona...
