- W2243316954 abstract "Preparation of activated carbons from sago wastes were investigated in this study. The rawmaterial of sago wastes was first pyrolysed in a pyrolysis reactor in inert condition for a totalof 3 minutes. The samples was subjected with N2 gas for 30 minutes to get an inertenvironment inside the quartz reactor before exposing the samples to microwave action forat least 3 minutes. The char sample was added with 50 % H2SO4 and 50% Na2SO4 foractivation. The adsorption rate has been studied under several parameters like adsorbentdosage, initial concentration, pH and agitation time with three types of heavy metals, whichinclude Lead, Pb(II), Copper, Cu(II) and Chromium, Cr(II). The adsorption parametersinfluenced on the adsorption rate were analyzed using Langmuir and Freundlich isotherm.The characteristics of the sago waste activated carbon were also investigated by studying themoisture content, ash content, volatile matter content, fixed carbon, surface morphology(SEM) and functional groups (FT-IR). Batch Adsorption test showed that the adsorptions ofPb(II), Cu(II) and Cr(II) metal ion differ for each parameter. According to the evaluationusing Langmuir equation, the monolayer adsorption capacity obtained were 0.4464 mg/g,0.0371 mg/g and 3.5714 mg/g for Pb(II), Cu(II) and Cr(II) respectively." @default.
