The coconut (Cocos nucifera) is highly nutritious and rich in fiber, vitamins, and minerals. Coconut palms are grown in more than 80 countries of the world, with a total production of 49 billion nuts. Coconut wastes such as coir pith, coconut bunch waste, coconut husk, copra meal, male flowers of coconut tree, etc. have been widely explored as adsorbents for the removal of various pollutants from water. Coir pith waste was used for the adsorptive removal of Pb(II) from aqueous solution by Kadirvelu and Namasivayam [135]. The adsorption capacity was reported to be 263 mg/g for Pb(II) removal which was found to increase with increasing pH from 2 to 4 and remained constant up to pH 10..
