Dried hyacinth root (DHR) powder is very efficient and provides a cost effective method for removing arsenic from water. There are various biosorbent available which are efficient in removing heavy metals. The present study successfully assess the potential of dried powder of hyacinth root (Eichhornia Crassipes (Mart.) Solms), referred as dried hyacinth root (DHR), by determining the effective size and pH at which it is capable of removing arsenite (As III) efficiently. At different size and pH, the experiment was conducted. Results from ICP-OES suggest that at 0.063mm, and at pH 6.2 to 8.2, DHR was more effective in mitigation of arsenic whereas at bigger size, that is, 4.1 mm, and at pH 2.2 and 4.2, DHR was not very effective. It is concluded that at finer size (0.063 mm), and at pH 6.2 to 8.2, DHR have more potential to remove arsenic from water.
