Industries are among the largest global consumers of water, with a significant portion being converted into industrial wastewater. Paint factories, in particular, are major contributors to environmental lead pollution, releasing lead (II) through untreated effluents. Exposure to lead (II) poses serious health risks, including carcinogenic effects, neurological disorders, blood-related complications, and damage to vital organs such as the liver, kidneys, and lungs. While extensive research has focused on lead (II) removal from synthetic wastewater, limited studies have addressed the application of these methods to real industrial wastewater. This study aimed to evaluate the efficiency of Noug stalk activated carbon in removing lead (II) from paint factory effluent under optimized conditions. Laboratory experiments were conducted to assess the performance of Noug stalk activated carbon in treating wastewater from a paint factory. Statistical analysis using Statistical Package for Social Sciences version 20 was employed, with a paired sample
