• W4285398239 abstract "Electronic waste also known as (E-waste) includes used computers, televisions, refrigerators, mobile phones, laptops, electric and electronic cables and so on possess a severe threat to the society and the environment. Among the Sustainable Development Goals (SDGs) about six goals are interlinked to tackle the e-waste management stress to understand and focus on the challenge. In the present work, we report the utilization of waste aluminum cables as high-performance modified electrode to detect the uric acid in human urine. The obtained waste PVC wrapped 2mm diameter aluminum cable is peeled off, cleaned and cut in to 7 cm rod to be use as an electrode. MoS 2 and Multiwalled Carbon Nanotubes (MWCNTs) doped MoS 2 are separately grown on the Al rod through hydrothermal synthesis. The XRD patterns reveal that both the MoS 2 and MWCNTs/MoS 2 are in 1T phase structures, but the doping of MWCNTs promoted a minor phase shift and transformed to accurate 1T structure. The fundamental modes of vibration and qualitative chemical analysis are obtained from FTIR and Raman analysis. The interlaced nanosheets underlying in flower like morphology of MoS 2 and MoS 2 /MWCNTs are clearly seen from the FESEM images which offered the high sensing ability of the sensor with a detection limit of 1.13 µM and sensitivity of 97.6 nA µM -1 with linear response (R 2 =0.99) within 2 seconds. The stability and reproducibility of the electrodes were determined by 15 repeated cyclic voltammetry response to 0.1M uric acid. All the detection parameters were studied in comparison with MoS 2 and MWCNTs/MoS 2 electrode and the later offered the superior results as mentioned. Though there are many publications on uric acid detections through nanomaterials modified standard electrodes, the present work initiates to report the non-enzymatic detection of uric acid in human urine samples by modifying the Al electrode for the e-waste. This work may pave the way towards decreasing the usage of conventional fossil carbon electrodes. The developed MWCNTs/MoS 2 electrode offers a super ultra-fast and highly-Sensitive electrode that can be employed in biomedical sensing applications.
