Abstract
Kontaminan yang menjadi perhatian atau Contaminants of Emerging Concerns (CECs) seperti zat warna merupakan permasalahan yang harus diatasi karena berdampak negatif bagi lingkungan dan kesehatan. Salah satu teknologi dalam menangani CECs adalah dengan pemanfaatan teknologi membran, khususnya mixed matrix membrane (MMMs). Penelitian ini bertujuan untuk mengembangkan filler baru, yaitu ZnO@gCN untuk meningkatkan performa penghilangan CECs, khususnya metilen biru (MB). Sintesis ZnO@gCN dilakukan melalui metode One Pot Thermal Decomposition. Sementara fabrikasi MMMs dilakukan dengan metode inversi fasa dengan variasi filler pada membran. Keberhasilan sintesis filler dan fabrikasi membran dikonfirmasi melalui karakterisasi FTIR, XRD, dan SEM. Penambahan ZnO mengakibatkan pecahnya cincin triazin pada gCN sehingga menghasilkan ikatan C-N baru serta dapat meningkatkan aktivitas fotokatalitik dari gCN. Performa MMM terbaik didapatkan pada membran dengan filler ZnO@gCN 0,1%, dengan menurunkan kadar MB hingga 97,72% di bawah radiasi sinar ultraviolet. Sampel yang sama, dapat menurunkan kadar MB hingga 97,44% dalam ruang gelap. Hasil yang diperoleh menunjukkan bahwa membran PVDF/ZnO@gCN memiliki kinerja yang paling baik dibandingkan dengan membran lainnya.
===========================================================
Contaminants of concern (CECs), such as dyes, are a problem that must be addressed because they have a negative impact on the environment and health. One of the technologies for dealing with CECs is the utilization of membrane technology, especially mixed matrix membranes (MMMs). This research aims to develop a new filler, ZnO@gCN, to improve the removal performance of CECs, especially methylene blue (MB). The synthesis of ZnO@gCN was carried out through the one-pot thermal decomposition method. Meanwhile, the fabrication of MMMs was carried out using the phase inversion method with a variety of fillers in the membrane. The success of filler synthesis and membrane fabrication was confirmed through FTIR, XRD, and SEM characterization. The addition of ZnO resulted in the breaking of the triazine ring on gCN to produce a new C-N bond and increase the photocatalytic activity of gCN. The best MMM performance was obtained in the membrane with 0.1% ZnO@gCN filler, with MB removal up to 97.72% under ultraviolet light radiation. The same sample can remove up to 97.44% MB in a dark room. The results obtained show that the PVDF/ZnO@gCN membrane has the best performance compared to other membranes.
