What is it about?
VPum and VSco are aboundantly found in many parts of the world. Thus, low-cost adsorbents, pumice (VPum) and scoria (VSco) were investigated for the removal of Cu(II) as function of various parameters using batch experiments observing the influence of Cd(II) and Ni(II) alongside. Kinetic data showed a trend of fast removal at initial stages, thereby achieving maximum adsorption after 1 h agitation. Adsorption capacity were found 1.432 and 1.015 mg/g using VPum and VSco, respectively. This work showed the promising nature of pumice and scoria to effectively remove copper from water.
Why is it important?
-The adsorbent used is cost effective and applicable easily -The nature of adsorbents, microvesicular texture, and porosity enhance surface area and is promising for amending too.
