Typha orientalis, commonly known as bulrush, bullrush, cumbungi in Australia, or raupō in New Zealand, is a perennial herbaceous plant in the genus Typha. It can be found in Australia, New Zealand, Malaysia, Indonesia and the wider western Pacific. T. Orientalis is a wetland plant that grows on the edges of ponds, lakes and slow flowing rivers and streams. Raupō was quite useful to the Māori. The Rhizomes were cooked and eaten, while the flowers were baked into cakes. The leaves were used for roofs and walls and occasionally for canoe sails. [2] The Māori introduced raupō to the Chatham Islands. Activated carbon was prepared from an inexpensive and renewable carbon source, Typhaorientalis, by H3PO4 activation and then impregnated with different Mn salts and tested for its Neutral Red (NR) adsorption capacities. The amount of Mn impregnated in the activated carbon was influenced by the anion species.
