With this consideration, the current work presents the detection and removal of a representative dye (congo red) of the azo class. The detection objective was achieved by the designing of an electrochemical sensor comprising of multi-walled carbon nanotubes (MWCNTs) loaded over the surface of glassy carbon electrode (GCE). While the removal objective was achieved by using graphene oxide (GO) nanosheets as adsorbent and BaO nanoparticles as photocatalyst. The designed sensing platform was found highly sensitive for congo red detection as authenticated by the LOD value of 0.1 nM. Congo red was photocatalytically removed from wastewater using BaO nanoparticles. The photocatalytic degradation led to 95 % removal in 90 minutes under acidic conditions. Adsorption method was also used for wastewater purification from congo red. The adsorption results leading to 100 % removal of the dye were modeled to assess the mechanisms and kinetics of adsorption. Cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) were employed to characterize both modified and bare glassy carbon electrodes. The CV results demonstrated that the modified GCE exhibited a larger surface area compared to the unmodified GCE, while the EIS revealed efficient charge transfer through MWCNTs/GCE as compared to the bare GCE.

Batch experiments of Cu(II) removal using waste tea leaves were conducted to examine the effects of operating parameters such as initial Cu(II) concentration and solution pH on the dynamic biosorption kinetics of Cu(II). The biosorption capability was found to be relatively low at highly acidic solution pH and intensified with increasing pH. After the Cu(II) removal reached the maximum biosorption capability at pH 5, it was suppressed at a higher solution pH. With increasing solution pH, the number of negatively charged active sites increased due to the facilitation of the deprotonation of functional groups on the surface of waste tea leaves. As a result, the biosorption of Cu(II) through the surface complexation mechanism was further promoted. When the solution pH exceeded 5, the proportion of Cu<sup>2 +</sup> in the solution decreased and the contribution of surface precipitation of Cu(OH)<sub>2</sub> dominated.
