Preparation of Carbon Nanosphere From Bamboo And Its Use In Water Purification

Bamboo naturally acts as an antibacterial and antifungal agent and is capable of absorbing chlorine, bad odor and toxic substances from water as well as it also replaces with healthy minerals like sodium, potassium and iron transforming ordinary water into mineral water. In this paper, nanosphere was prepared by carbonizing pieces of bamboo in muffle furnace at 600oC under in-sufficient air. The black mass so obtained was functionalized with conc. nitric acid. It was then characterized by SEM, TEM, XRD, AFM etc. This was then treated with different metals to increase its absorption efficiencies. Considering the properties of bamboo, it was thought to develop an eco-friendly and cost effective water purification system using the nanospherical bamboo charcoal, requiring less efforts compared to other existing techniques. After doing the preliminary tests, it was found that this purification technique is able to remove arsenic and fluoride completely from the water.
