Pengaruh pH dan Waktu Reaksi terhadap Efisiensi Penurunan Kadar Mikroplastik Jenis Polystyrene pada Limbah Cair Sintetis dengan Metode Elektrokoagulasi

Abstract

One type of plastic polymer that can produce microplastics is polystyrene. When plastic waste is thrown into water, it can gradually decompose through chemical, physical and biological processes, producing microplastics, which are small plastic particles. Microplastics can enter the food chain and undergo biomagnification. One processing method that can be used to reduce the amount of microplastics is electrocoagulation. The aim of this research is to find out how effective electrocoagulation is in reducing levels of polystyrene microplastics. This is done by applying variations in pH and residence time in minutes. In this study, the ideal microplastic removal efficiency level was 73.70%.
