In this study, we have expanded our previous investigation by studying CD and ABS assisted dye removal process from contaminated water using self-propelling chemically driven MnO2 micromotors. The decolorization efficiency is observed to decrease in increasing concentration of dye content in the solution. The quantity of MnO2 particles is the limiting factor for the removal of dye, whereas the concentration of H2O2 also plays an important role when decolorization of concentrated dye solution is desired. A too high concentration of the fuel may rapidly degrade the MnO2 particles and can be detrimental for the remediation process. The role of surfactant is to facilitate bubble formation and its concentration should be kept to a minimum level as it is an additional contaminant. However, its absence drastically hampers the decolorization efficiency. MnO2 particles, thus, hold a great promise for the removal of toxic organic dyes from contaminated water. Further studies for the removal of other pollutants, such as pesticides, antibiotics, and heavy metals, should be performed.
