Abstract

Pesatnya perkembangan teknologi didalam perindustrian menghasilkan limbah logam berat yang termasuk dalam limbah B3, sehingga diperlukan adanya pengolahan agar tidak merusak ekosistem dan kehidupan di sekitarnya. Salah satu industri yang membutuhkan pengolahan limbah B3 adalah industri electroplating yang mengandung unsur logam salah satunya adalah kromium. Salah satu metode yang digunakan untuk meregenerasi limbah logam berat adalah zwiterionic betaine gel, namun kekurangan dari metode ini adalah adanya asosiasi intra-intrachain sehingga kemampuan ionic group untuk mengadsorpsi ion terhambat oleh interaksi charge group tersebut. Penelitian ini dilakukan untuk menghindari adanya asosiasi intra-intra chain, gel disintesis secara terpisah dengan menggunakan kopolimer NIPAM-co-kitosan dan NIPAM-co-asam akrilat. NIPAM-co-kitosan dan NIPAM-co-asam akrilat gel disintesa melalui reaksi polimerisasi menggunakan N,N'-methylenebisacrylamide (MBAA) sebagai crosslinker dengan perbandingan konsentrasi NIPAM-co-kitosan dan NIPAM-co-asam akrilat masing-masing 9:1, 8:2, 7:3, dan 6:4 pada suhu 10 oC. Logam berat akan teradsorpsi secara simultan oleh charge group didalam gel dan terdesorpsi dengan kemampuan thermosensitive NIPAM. Berdasarkan hasil analisa FTIR pada gel NIPAM-co-kitosan dan NIPAM-co-asam akrilat, masih ditemukan sedikit vinyl group pada gugus fungsinya. Dapat disimpulkan bahwa sintesis kopolimer gel yang dilakukan sudah berhasil karena hasil analisa sintesis sudah membentuk gel walaupun masih terdapat vinyl group yang bereaksi. Sedangkan berdasarkan hasil analisa swelling degree pada limbah electroplating, hasil terbaik didapatkan pada konsnetrasi 8:2.

The rapid development of technology in industry produces heavy metal waste which is included in B3 waste, processing is needed so as not to damage the ecosystem and the surrounding life. One industry that requires B3 waste processing is the electroplating industry which contains metal elements, one of which is chromium. One method used to regenerate heavy metal waste is zwiterionic betaine gel, but the weakness of this method is that there is an intra-intrachain association so that the ionic group's ability to adsorb ions is inhibited by the charge group interaction. This study was conducted to avoid the existence of intra-intra-chain associations, the gel was synthesized separately by using NIPAM-co-chitosan and NIPAM-co-acrylic acid copolymers. NIPAM-co-chitosan and NIPAM-co-acrylic acid gel were synthesized through a polymerization reaction using N, N'-methylenebisacrylamide (MBAA) as a crosslinker with a comparison of the concentrations of NIPAM-co-chitosan and NIPAM-co-acrylic acid respectively 9: 1, 8: 2, 7: 3, and 6: 4 at 10 °C. Heavy metals will be adsorbed simultaneously by a charge group in the gel and desorption with the thermosensitive ability of NIPAM. Based on the results of FTIR analysis on NIPAM-co-chitosan and NIPAM-co-acrylic acid gels, there was still a small amount of vinyl group in its functional group. It can be concluded that the synthesis of gel copolymers has been successful because the results of synthesis analysis have formed a gel even though there are still vinyl groups that react. While based on the results of the swelling degree analysis on electroplating waste, the best results are obtained at 8: 2 concentration.
