Daftar Isi:
- Methylene blue is a cation dyestuff that is often used in the textile industry, and is susceptible to being discharged into water because, this compound is only used about 5% while the remaining 95% will be disposed of as waste. The method of handling waste that is often done is to use a membrane. One of the superior polymers used as membranes is PVDF which is thermoplastic (strong) but has a lack of rejection which is less than the maximum which is usually caused by pore size that is too small so that it can easily be blocked (fouling). To overcome this, bentonite is added to the PVDF membrane in hopes of increasing rejection. Bentonite is then dispersed into a PVDF membrane that is made by phase reversal. PVDF membranes and PVDF-Bentonite composite membranes have been successfully made with porous, hydrophobic characterization, and by adding bentonites to the polymer will reduce the contact angle. PVDF-Bentonite composite membrane was successfully made with a thickness between 0.05-0.08 mm and an average pore size below 2 μm so that it is classified as an ultrafiltration membrane. After testing the separation ability of the PVDF-Bentonite composite membrane against the sample solution, it is known that the membrane rejection coefficient under optimum conditions is at 1 bar pressure and pH 5 with a rejection coefficient value of 82.65% and permeability of 19.197 Lm-2h -1bar-1 An increase in the rejection coefficient and permeability of the modified membrane where under the same conditions the usual ultrafiltration PVDF membrane has a rejection Synthesis and Characterization Nanofibers Membrane by electrospinning for Adsorption of Methylene blue coefficient of 76.45% and permeability of 8.921 Lm-2h1bar
