Adsorption-Photocatalytic Degradation Of Chicken Processing Wastewater Using Powdered Activated Carbon-Supported Graphitic Carbon Nitride

Due to the expansion of agricultural sector, a massive volume of chicken processing wastewater has been produced and the conventional technologies are ineffective to remove organic and inorganic compounds. Thus, this project will solely investigate the performance for the adsorption-photocatalytic d...
