Effect of Heating Temperature and Time of Coffee Waste on The Adsorptivity of Formaldehyde

Abstract

This study was conducted to examine the potential use of coffee waste (CW) as an adsorbent of HCHO by adding into fiberboard. For the purpose, CW treated with various temperatures and times was placed in desiccator with a HCHO solution and then the HCHO adsorptivity of the CW was measured by acetylacetone (ATAN) and DNPH
