摘要：
A water purifier consisting essentially of manganese dioxide particles having a 20 to 48 mesh size and macroscopic pores which are so large in size as to permit passage of water therethrough. The particles may have active sites of needle-like or columnar crystals of manganese dioxide on the surfaces thereof. A method for making such water purifier is also described.
