Abstract

Dalam beberapa tahun terakhir, industri kimia dan metalurgi telah mengalami pertumbuhan yang cepat yang menyebabkan peningkatan produksi limbah, termasuk kontaminan logam berat dalam air. Membran polimer HDPE, menawarkan solusi potensial karena karakteristiknya yang ramah lingkungan dan biaya yang rendah. Untuk meningkatkan sifat dan performa dari membran HDPE, dilakukan penambahan material pengisi komposit karbon-zeolit (KKZ) yang memiliki potensi dalam meningkatkan hidrofilisitas membran dan kemampuan membran untuk menghilangkan logam berat. Pada penelitian ini, dilakukan fabrikasi membran HDPE/KKZ dengan pelarut mineral oil, menggunakan konsentrasi optimum 15% (%b/b) berdasarkan penelitian sebelumnya, dengan tambahan variasi komposisi pengisi 0,5%; 1% dan 1,5% untuk melihat pengaruhnya terhadap karakteristik dan kinerja yang dihasilkan. Membran yang difabrikasi akan dikarakterisasi dengan menggunakan uji kuat tarik, FTIR, XRD, SEM-EDS, sudut kontak, porositas, dan uji kinerja membran. Hasil karakterisasi telah menunjukkan bahwa penambahan KKZ pada membran HDPE mampu meningkatkan kekuatan mekanik membran. Membran HDPE/KKZ mencapai kinerja pemisahan mencapai 80,35% dan 70,76% pada logam Ni dan Pb 50 ppm, namun fluks yang dihasilkan sangat rendah, sebesar 0,4159 L m^-2.jam^-1 dan 3,197 L m^2.jam^-1.

In recent years, chemical and metallurgical industries have experienced rapid growth leading to increase waste production, including heavy metal contaminants in water. HDPE polymer membrane offers a potential solution due to its environmentally friendly characteristics and low cost. To improve the properties and performance of HDPE membranes, carbon-zeolite (KKZ) composite as a filler material is added, which has the potential to improve the hydrophilicity of the membrane and the ability of the membrane to remove heavy metals. In this study, HDPE/KKZ membrane was fabricated with mineral oil solvent, using an optimum concentration of 15% (%b/b) based on previous research, with additional variations in filler composition of 0.5%; 1% and 1.5% to see its effect on the characteristics and performance produced. The fabricated membranes were characterized using tensile strength, FTIR, XRD, SEM-EDS, contact angle, porosity, and membrane performance tests. The characterization results have shown that the addition of KKZ to HDPE membranes can increase the mechanical strength of the membrane. HDPE/KKZ membrane achieved separation performance of 80.35% and 70.76% at 50 ppm Ni and Pb metals, but the flux produced was very low, amounting to 0,4159 L m^2.h^-1 and 3,197 L m^2.h^-1.
