Abstract
Hemodialisis adalah prosedur medis yang penting untuk membersihkan darah dari racun dan kelebihan cairan ketika fungsi ginjal terganggu. Namun, proses hemodialisis menghasilkan produk sampingan berupa air dialisat yang digunakan sebagai limbah medis. Tujuan dari penelitian ini adalah untuk menyelidiki potensi penggunaan mixed matrix membrane adsorbers (MMMAs) dengan menggunakan pengisi seperti MIL-100 (Cr) dalam matriks PES untuk menyisihkan urea dan kreatinin pada air dialisat bekas hemodialisis. Preparasi MMMAs PES/MIL-100(Cr) dilakukan dengan menggunakan metode non-solvent induced phase solution (NIPS) dengan air demineralisasi sebagai larutan non-pelarut. MMMAs PES/MIL-100(Cr) menunjukkan pola difraksi sinar-X dan FTIR dengan puncak-puncak karakteristik khas polimer PES yang mampu meningkatkan kristalinitas dari 34,1% menjadi 47,21% dan MIL-100(Cr) tidak memiliki ikatan kimia dengan polimer PES. Penambahan MIL-100(Cr) sebesar 0,1% dapat meningkatkan sudut kontak membran dari 56,76o menjadi 75,2o yang mengindikasikan MMMAs lebih banyak menahan air. Pada pemisahan urea dan kreatinin, MMMAs PES/MIL-100(Cr) menunjukkan kinerja yang lebih baik daripada membran dengan fluks air 23,8 L/m2jam, rejeksi urea 33,67% dan rejeksi kreatinin 18,65%. MMMAs PES/MIL-100(Cr) menunjukkan penurunan fluks air menjadi 18 L/m2jam tetapi mampu meningkatkan rejeksi urea menjadi 38,63% dan rejeksi kreatinin menjadi 47,29%. Dalam konteks adsorpsi, MIL-100 (Cr) / PES MMMAs menunjukkan kapasitas adsorpsi yang lebih baik daripada membran PES untuk urea dari 6,07 mg/g menjadi 20,75 mg/g dan kreatinin dari 0,26 mg/g menjadi 1,56 mg/g.

Hemodialysis is an important medical procedure to cleanse the blood of toxins and excess fluid when kidney function is impaired. However, the hemodialysis process produces by-products in the form of used dialysate water as medical waste. The aim of this study was to investigate the potential use of mixed matrix membrane adsorbers (MMMAs) using pengisis such as MIL-100(Cr) in PES matrix for urea and creatinine removal in spent hemodialysis dialysate water. Preparation of MIL-100(Cr)/PES MMMAs was carried out using non-solvent induced phase solution (NIPS) method with demineralized water as non-solvent solution. MIL-100(Cr)/PES MMMAs showed X-ray diffraction and FTIR patterns with characteristic peaks typical of PES polymer which was able to increase the crystallinity from 34.1% to 47.21% and MIL-100(Cr) had no chemical bond with PES polymer. The addition of MIL-100(Cr) at 0.1% can increase the membran contact angle from 56.76o to 75.2o which indicates MMMAs retains more water. In the separation of urea and creatinine, MIL-100(Cr)/PES MMMAs showed better performance than the membrane with water flux of 23.8 L/m2h, urea rejection of 33.67% and creatinine rejection of 18.65%. MIL-100(Cr)/PES MMMAs showed a decrease in water flux to 18 L/m2h but was able to increase urea rejection to 38.63% and creatinine rejection to 47.29%. In the context of adsorption, MIL-100(Cr)/PES MMMAs showed better adsorption capacity than PES membrane for urea from 6.07 mg/g to 20.75 mg/g and creatinine from 0.26 mg/g to 1.56 mg/g.
