Design of carbon dioxide absorption from polluted city air

Global climate change is the most serious environmental problem which the world is facing now. To avoid dangerous climate change, the growth of atmospheric concentrations of greenhouse gases must be halted and may have to be retarded. The concentration of carbon dioxide, CO2, the most dominant green...
