Reduction of Cd(II), Ag(II) AND Cu(II) Using Rubber Seed Shell : Adsorption Isotherm and Kinetics

Increasing industry in Malaysia produce high amount of wastewater, thus increase the heavy metal contaminants that become global concern of environment. Adsorption of heavy metals by activated carbon will need higher cost compare to the other adsorbents. Thus, an alternative way of waste utilization...
