Abstract
Penelitian studi transpor kreatinin dengan membran PIM bertujuan untuk menghasilkan membran selektif dari beberapa variasi komposisi yang berikutnya akan ditentukan membran terbaik berdasarkan stabilitas dan efektifitas transpor kreatinin pada fasa umpan. Membran PIM dengan polimer penyusun CTA (Selulosa triasetat) dilarutkan terlebih dulu dilarutkan dalam kloroform dengan pengaduk magnet selama kurang lebih 2 jam. TBP (Tributil fosfat) sebagai senyawa pembawa dan 1- Dekanol sebagai pemlastis dicampurkan kedalam larutan membran dan dilakukan pengadukan kembali. Larutan membran didiamkan pada suhu ruang selama 24 jam. TBP dalam membran berperan sebagai senyawa yang akan mengangkut kreatinin dari fasa umpan menuju fasa penerima. Membran PIM yang dihasilkan kemudian diuji sifat fisiknya dengan uji sudut kontak, swelling degree, uji ketebalan, dan dikarakterisasi menggunakan FTIR. Konsentrasi pada fasa umpan hasil uji transport diukur dengan spektrofotometer UV-Vis. Hasil penelitian membahas variasi membran PIM terbaik ditinjau dari stabilitas dan laju transpor. Hasil akhir diperoleh variasi membran 8:1:2 memiliki laju transport paling efektif pada konsentrasi 75 ppm sebesar 46,68%. Sedangkan pada membran 5:4:1 memiliki stabilitas terbaik ditinjau dari ketebalan membran dan swelling degree. Namun laju transpor juga harus menjadi pertimbangan untuk menilai efisiensi membran dalam melakukan transpor kreatinin
English Abstract
The study of creatinine transport with PIM membrane aims to produce selective membranes from several composition variations which will then determine the best membrane based on the stability and effectiveness of creatinine transport in the feed phase. PIM membrane with the constituent polymer CTA (Cellulose triacetate) was dissolved first dissolved in chloroform with a magnetic stirrer for approximately 2 hours. TBP (Tributyl phosphate) as a carrier compound and 1-Decanol as a plasticizer were mixed into the membrane solution and stirred again. The membrane solution was allowed to stand at room temperature for 24 hours. TBP in the membrane acts as a compound that will transport creatinine from the feed phase to the receiving phase. The resulting PIM membrane was then tested for physical properties by contact angle test, swelling degree, thickness test, and characterized using FTIR. The concentration in the feed phase of the transport test results was measured with a UV-Vis spectrophotometer. The results discussed the best PIM membrane variation in terms of stability and transport rate. The final results obtained 8:1:2 membrane variation has the most effective transport rate at a concentration of 75 ppm of 46,68%. While the 5:4:1 membrane has the best stability in terms of membrane thickness and swelling degree. However, the transport rate must also be taken into consideration to assess the efficiency of the membrane in transporting creatinine
