Portable Fume Hood as an Environmentally Friendly Laboratory Tool to Neutralize Acid Contamination

Abstract

A portable fume hood design with an acid pollution absorber filter was prepared. This study aims to: (1) make a portable fume hood equipped with an acid contaminant absorbent filter housing, and (2) determine the length of time the ability of the lime granule can function as an acid contaminant absorbent filter. This study is a quasi-experimental study using posttest only with control group design to assess the feasibility of using lime granules as acid absorbent filters on portable fume hoods. Data analysis was performed by regression using the Excel program. The results of the study are as follows: (1) portable fume hood that use acid-absorbent filters have been made, (2) The average length of time the ability of lime granules can function as an acid contaminant absorbent filter on the use of a portable fume hood at a lime granule weight of 0.5; 1,0; 1,5; and 2.0, respectively 222, 589, 880, and 1219 minutes. This relationship can be estimated with a regression equation Y = 0.619X -36.71. Which Y is the ability of lime granule as absorbent of acid contamination, and X is the weight of lime granule.
