Optimalisasi degradasi metilen biru menggunakan komposit mno/arang cangkang k…

Water pollution caused by synthetic dye waste such as methylene blue (MB) has become a serious environmental issue due to the stable, toxic, and persistent nature of MB. To address this problem, research was conducted with the aim of optimizing the degradation process of methylene blue using a MnO/ACKS composite. This composite was synthesized via a sol-gel method and calcined for durations ran…
