The Effectiveness of the Absorption of CO, CH4, CO2, H2S and Pb Gasess by a Mixture of Sansiviera and Coffee Powder

Abstract

This study aims to analyze the effectiveness of the absorption of CO, CH4, CO2, H2S and Pb Gasses by a mixture of Sansiviera and Coffe Powder. Gas measurements were carried out using a Multitec 250 gas detector, while Pb levels were analyzed using AAS. The results showed that the mixture of Sansevieria and coffee powder effectively absorbed CH4, CO2, H2S and Pb gases with the highest effectiveness, respectively 87.5%, 71.06%, 55.5% and 59% with the composition of sansiviera: coffee in the sample respectively 50:50; 50: 0; 30:20; 40:10. Meanwhile, the mixture of sansiviera and coffee was slightly effective in absorbing CO gas with the highest effectiveness of 15.65% at the composition of 50: 0.
