Removal of nickel from industrial effluent using a synergistic mixtures of acidic and solvating carriers in palm oil-based diluent via supported liquid membrane process

The utilization of environmentally benign diluent of palm oil in the supported liquid membrane (SLM) process is able to reduce both environmental and economic problems due to the consumption of the petroleum-based diluent. A preliminary study has been conducted on the removal of nickel ion via SLM u...
