Abstract
We demonstrate in detail the use of self-propelling manganese oxide (MnO2) microparticles for water remediation. The particles exhibit removal of organic dyestuff from water following chemical degradation and adsorptive bubble separation mechanisms. The effect of various parameters such as dye concentration, remediation time, quantity of MnO2 particles and fuel concentration is studied to determine optimal parameters for the assessment of their potential in practical applications. A combined effect of two efficient remediation mechanisms allow fast removal of organic dyes from water in ca. 2 min. A low cost, transient lifetime and environment friendly nature of MnO2 offers a high potential of dynamic water remediation tasks at remote waterbody locations.
