Titanium dioxide (TiO₂) nanoparticles are synthesized by a sol-gel combustion process using aloe-vera gel as precursor. Green synthesized TiO₂ nanoparticles are chemically stable, low toxic, low pollutant load, ecofriendly and cost effective. Due to high surface-to-volume ratio nano-sized TiO₂ is highly photocatalytic and hence with help of them, the wastewater remediation is well performed. The TiO₂ nanoparticles size has been reduced for increasing the reactive surface area to improve efficiency of the photocatalyst. TiO₂ photocatalyst degrade many organic and inorganic pollutants effectively and turn into CO₂ and other harmless inorganic anions. By adding TiO₂ nanoparticles in wastewater, the dissolved oxygen and p^H value of water both increase and further increase with time of fall of UV radiation. The kurtosis, skewness and correlation parameter of the given data are determined and discussed. The statistical results are strongly consistent with the spectral behaviour of the dissolved oxygen and p^H value of the water.
