Abstract:
This research aims to study the efficiency of plants carbon dioxide absorbability in
plants in the green areas, the relation between temperature on the leaf and absorption of carbon
dioxide (CO2
), and evaluation the absorption of CO2
by the thermal imaging camera. In this
experiment, the CO2 was added into the chamber with size of1.25 m
3
and finished when the
concentration of CO2 was stable. After that, the concentrations of CO2 were recorded and the
temperatures were measured using the thermal imaging camera every 5 minutes for 5 hours. The
samplings of plants, which were suitable to growth in green areas, had 6 types consisting of
perennials absorption CO2
in the high-level, middle-level and low-level, the shrub absorption CO2
in the high-level, middle-level and low-level that had 2 species of each type.
From the experiment results, we found that the most efficiency absorption CO2was the
high absorbent shrub type with the average absorption time of3 hours 57 minutes. It was able to
reduce the maximum CO2
concentration of243 ppm. The low absorbent shrub type had the most
consumption time and the least changing CO2
concentration of69 ppm. The least average
temperature from thermal imaging camera of leaf area was32.11◦C. Analysis of the relation
between the leaf temperature and CO2
absorbability from each species by Multiple Linear
Regressionequation, we discovered that most efficient CO2
absorbability washibiscus. Thus, the
equation of the carbon dioxide absorbability (ppm) was 1,510.8550.008 X1
