Application Of Okra (Abelmoschus Esculentus) Mucilage-Based As Natural Coagulant In Domestic Wastewater Treatment

This research investigates water treated extraction (AEaqs) of carbohydrate coagulants from okra (Abelmoschus esculentus) and inspects its chemical characteristics (i.e. isoelectric point (IEP) and Fourier Transform Infrared). AEaqs serves as anionic coagulants to boost bridging mechanisms by carbox...
