  • How can nickel (Ni) be recovered from wastewater?
  • The research demonstrated the recovery of Nickel (Ni) from wastewater through synergistic interactions between electrocatalytic oxidation and electrodeposition processes. Electrochemical tests used a direct current power supply in constant current mode, with the positive pole on IrO 2 /Ti mesh and negative pole on stainless steel.
  • Does electroless nickel plating reduce water pollution?
  • Current density, pH, and nickel ion concentration were analyzed for improved recovery. Achieved nearly 99% Ni 2+ recovery via chemical-free, cost-effective method for sustainable wastewater treatment. This study was conducted to address water pollution concerns entwined with electroless nickel plating (ENP) industry.
  • How is ni recovered from ENP wastewater?
  • The nickel complex undergoes direct oxidation and subsequent decomposition, leading to discharge of free Ni ions and successful Ni recovery from the ENP wastewater. The substance recovered from the electrodes was unequivocally identified as zero-valent Ni through application of XRD, SEM, and EDS analysis.
  • Is nickel waste biodegradable?
  • This waste exhibits considerable stability and is not biodegradable. In addition to its pronounced deleterious impact on the environment, the discharge of wastewater containing nickel also raises a notable apprehension pertaining to potential risks to human health.
