Abstract
The presence of Co2+ and Ni2+ in water is a major concern owing to their non-biodegradable, carcinogenic and mutagenic nature. In recent years, diverse techniques have been applied in their removal from water and upon careful evaluation of some of these techniques, adsorption seemed to be a desirable technique of choice owing to its favourable characteristics as well as its benefits in Co2+ and Ni2+ removal. By virtue of the efficacy of adsorption being governed by an adsorbent, Hollow Carbon Nano Spheres (HCNS) have emerged as attractive adsorbents of choice due to their favourable characteristics in comparison to the adsorbents which have previously been applied in the removal of Co2+and Ni2+ from water...
