Our Students Participated in the Colorimetry Workshop in HKBU
10 S.4 students participated a colorimetry workshop organized by HKBU in late June. By applying the principles of colorimetry, students can monitor the level of nitrogen dioxide in the air. After setting up a few passive air samplers in the laboratory and roadside, students went back and listened to the professors about the principles behind of the workshops. At last, students can find the level of the air pollutants by using the mobile application “ChemEye” to detect the colour intensity.
