Adsorption of Ni(II) onto Chemically Modified Spent Grated Coconut (Cocos Nucifera)
A new adsorbent of plant waste origin from coconut processing food factory was explored for removing Ni(II) from aqueous solutions. Several parameters such as pH, dosage, concentration and contact time were studied to obtain optimum conditions for treatment of Ni(II) contaminated wastewater. Spent g...
