"Adsorption of Odorant Chemicals by Activated Carbon from Spent Coffee Grounds"Research Goal: Aims to investigate the effect of pH on the adsorption isotherms of activated carbon from SCG.Objective: to determine the effect of pH on the adsorption isotherm of activated carbon derived from SCG on different odorant chemicals.a. determine the adsorptive properties of activated carbon derived from SCG for the removal of odorant chemicals from solution.b. determine the effect of pH on the adsorption isotherms of SCG using odorants as adsorbates.-typical activated carbon have surface areas of approx. 1000 m^2/g and pore volume over 1 cm^3/g.-superior adsorption properties of activated carbon are linked to their high surface areas and pore volumes-physical adsorption is not specific for certain applicationsSCG derived activated carbonfrom bandosz2015-physical activation-from coffee endocarp(lignocellulosic residue)-CO2-->400 to 1300 m2/g-by steam-->630 m2/g-chemical activation-->2030 m2/g-It was concluded that the porous propertiesof the coffee-derived carbons were similar to those of activated carbons obtained from other cellulose-containing precursors, such as macadamia nut shells-
