Title: PM 2.5 sensing device using conductivity of the solution
Inventor: YOO SEUNG HYUN
IPC: G01N15/06
Filed: 2018-09-18
Abstract: The present invention relates to an ultra-fine dust measuring method in a solution. According to the present invention, the degree of fine dust can be measured with an electrical conductivity value by considering fine dust as an ionic compound by collecting the fine dust in water by driving a filter device or a fan. It is observed that correlation with a laser scattering type fine dust measuring device having relatively high accuracy is obvious as a result of repeatedly experimenting a method of measuring the degree of fine dust several times. Therefore, the possibility of developing a new type of fine dust measuring device using an electrical conductivity method can be confirmed. Nitrate ion, nitrous acid ion, mineral values and acidity are measured by considering in that the chemical characteristics of the fine dust can be recognized even with a chemical test paper which can be easily purchased in a market. Therefore, it is confirmed that ionic compounds are largely contained as a fine dust component through a chemical test paper. The degree of the fine dust can be recognized with ppm or a micro-siemens μS/cm which is a conductivity value when electrical conductivity is measured after filtering the fine dust with a micro-filter and melting the same in a predetermined amount of distilled water on the basis of a factor that ions exist in the fine dust. The electrical conductivity method which is an indirect method of measuring the fine dust is performed with an experiment under an assumption that polluted air in the atmosphere is dissolved in the distilled water, and thus the electrical conductivity is increased by various toxic ions contained in the fine dust.
