Equilibrium and Kinetic of ultrasound-assisted adsorption of Chromium (VI) ion from electroplating wastewater using melon seed husk activated carbon

This study was focused on the removal of Cr(VI) ions from electroplating wastewater by ultrasound-assisted adsorption onto activated carbon obtained from melon seed husk. The activated carbon was produced by carbonization of crushed melon seed husk at a temperature of 500 °C for 15 min and further a...
