Introduction Triclosan is a common antibacterial drug identified as major contaminant in South African waters, notably Gauteng and KwaZulu Natal provinces. This comes from personal care products pharmaceuticals. It has been frequently detected local streams wastewater treatment plants, posing threat to aquatic ecosystems human health. Studies have emphasised the necessity of addressing presence triclosan water bodies lessen its harmful impacts on environment. Methods In this study, NaAlg/MnS x bio-nanocomposite hydrogel beads incorporated with different amounts MnS NPs (0.02–0.2 g) were synthesised via ionic gelation method employed an adsorbent for removal aqueous solutions. The surface charge, morphology, thermal stability, crystallinity, functional groups characterised by SEM equipped EDX, TEM, Thermogravimetric analysis, FTIR, XRD, zeta sizer (mV). Results discussions experimental results demonstrated that incorporating 0.02–0.2 g hydrogels led enhanced mechanical structure, porosity, swelling ability adsorption compared pristine NaAlg hydrogel. response methodology was used optimise parameters affecting batch onto adsorbent. Basic pH conditions suitable removing solutions hydrogen bonding carboxyl beads. pseudo-second order, Freundlich, Sips models better explained kinetics equilibrium isotherm data. maximum capacity estimated using Langmuir model 132 mg/g. thermodynamic (enthalpy (∆H) entropy (∆S)) found be 44.042 kJ/mol 207.018 J/Kmol, respectively, which means reaction endothermic increases randomisation at solid/liquid interface. Gibbs free energy (∆G) negative throughout studied temperature range, indicating process spontaneously energetically favoured.

The depletion of fossil fuels in the current world has been a major concern due to their role as primary source energy for many countries. As non-renewable sources continue deplete, there is need more research and initiatives reduce reliance on these explore better alternatives, such renewable energy. Hydrogen one most intriguing producing power from fuel cells heat engines without releasing carbon dioxide or other pollutants. production hydrogen via electrolysis water using sources, solar energy, possible uses solid oxide (SOECs). SOECs can be classified either oxygen-ion conducting proton-conducting, depending electrolyte materials used. This article aims highlight broad important aspects hybrid SOEC-based hydrogen-generating technology, which utilizes mixed-ion conductor capable transporting both oxygen ions protons simultaneously. In addition providing useful information technological efficiency SOEC, this review make efficient than any system.
