The present study aims to treat the effluents generated in Analytical Chemistry classes with filtration with activated carbon from residual coffee grounds at the UECE / FAEC Campus. Activated charcoal was prepared using chemical activator NaOH and calcined at 550 oC. The charcoal was characterized by X-ray and FTIR diffraction. The XRD results showed a material with an amorphous characteristic, whereas the FTIR confirmed vibrations around 1600 and 1400 cm-1 referring to the stretching of aromatic C-C and C = C bonds or lignin rings, typical of carbonaceous material. From the adsorption tests for three types of effluents, the results showed that the coal was efficient for the effluents of flasks 1 and 3 with 99% yield with 5 times reuse recycle, without loss of adsorption.
