| titleOfInvention | Method for detecting nano-particle pollutants in water based on functional micro-nano bubble enrichment and micro-fluidic separation combined technology |
| abstract | The invention provides a method for detecting nano-particle pollutants in water based on a functional micro-nano bubble enrichment and microfluidic separation combined technology, which comprises the following steps: firstly, introducing nano bubbles into a water sample to be detected, stirring, enriching nano particle pollutants, and then introducing micro bubbles, wherein when the volume ratio of the water sample to be detected, the nano bubbles and the micro bubbles is 5-12: 1: 2-3, introducing the water sample into the spiral microfluidic device for separation, and then taking the sample at the outlet of the spiral microfluidic device for qualitative and quantitative analysis and determination; the method is simple and convenient to operate, the unique performance of the micro-nano bubbles enables the micro-nano bubbles to have advantages in the aspect of removing nano particles, the possibility of efficiently enriching the nano particles is provided, the nano particles and the nano particles aggregates obtained by enrichment can be detected in a mode of arranging the nano particles and the nano particles aggregates into a single line or paving the nano particles and the nano particles aggregates on the liquid surface by selecting proper sorting force, micro-channel size, flow and the like aiming at the nano particles and the aggregates of the nano particles, and qualitative and quantitative characterization of trace nano particle pollutants in the environment can be realized. |
