Water purification method using plant molecules

Arsenic is a poisonous metalloid which, because of its hydroscopic nature, is primarily transported through water. Most plant species, including the nopal cactus, produce a sticky substance called mucilage. Mucilage swells in water but is insoluble and can precipitate ions, bacteria and particles from aqueous solutions. The invention includes a method of separating particulates and heavy metals such as arsenic (As) from drinking water using natural flocculants obtained from cactus mucilage. The
