All-fiber impurity collector based on laser-induced microbubble

Microbubbles have attracted interests in polluted water treatment industry. We proposed and constructed an all-fiber impurity collector based on the laser-induced microbubbles characteristics for polluted water treatment. Without any special pretreatment, such as metallically coating or carbon materials doping, the proposed impurity collector performed microbubbles generation and impurities extraction and collection. We employed the graphite oxide nanoplatelets in an aqueous solution to construct the polluted water environment to show the performance of the all-fiber impurity collector. With the optimal incident laser power of 11 mW, we performed the collection efficiency as high as 16.3×10 4 /s. The optimal microbubbles diameter was in the range of 80–120 μm. The proposed all-fiber impurity collector extends the potential applications of fiber-based optical manipulation for polluted water treatment.
