In this study, novel cellulose/carboxymethyl chitosan (CMCS) composite hydrogels were prepared by blending cellulose and CMCS in LiOH/urea aqueous solutions, then cross-linking with epichlorohydrin. The structure morphology of the characterized Fourier transform infrared spectroscopy, wide-angle x-ray diffraction, thermo-gravimetric analysis, scanning electron microscopy. results revealed that ...

Plastik sintetis yang digunakan sebagai pembungkus makanan dapat menimbulkan masalah lingkungan, karena sulit terurai sehingga menjadi sampah. Bioplastik alternatif plastik komersial terbuat dari bahan alami mudah terurai. Berbagai dasar pembuatan bioplastik telah ditemukan, salah satunya berbahan karagenan. memiliki kekurangan seperti teksturnya kaku dan rapuh, perlu ditambahkan gliserol pemla...

The present study aimed to investigate the potential application of chitosan (CS) and its two derivatives, dialdehyde (DCT) carboxymethyl (CMC), as new flocculants in purification filter backwash water. main objective work was remove disadvantages inconveniences associated with using synthetic flocculants, mainly based on polyacrylamide, by biodegradable non-toxic biopolymer flocculants. deriva...
