Water is an essential commodity in everyday life for every form of life. Though the water is the most abundant substance found in earth, still the usable/potable water resources are shrinking every passing day. One of the problems due to which the water gets contaminated is presence of dyes. This following review paper focuses on using an advanced technique involving adsorption of dye particles using ZnO nano particles. The ZnO nano particles are synthesized in the lab using simple precipitation method. The dyes are characterized by UV-Vis spectrophotometer and the ZnO nano particles characterized for its structural morphology using X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier trans-form IR (FTIR) analysis. The size of the nano particles is found out and the application of these NPs are tested at various concentrations of dyes at various pH. The adsorption mechanism is studied in line with Langmuir model using diverse literature available. The treated water possesses characteristics within the safe disposable limits and can be either disposed to any stream of water or used for any raw water intake.
