Abstract

Various separation techniques for separation of technetium-99m (99mTc) from molybdenum-99 (99Mo) are being developed to overcome the drawbacks of using 99Mo from neutron activation technique. Ionic liquids (ILs) were used in many extraction processes in metal separation due to their high selectivity. In this research, two benzotriazolium-based ionic liquids were used as co-extractant in 99mTc/ Mo separation process via liquid-liquid extraction. 1-octyl-3-methyl-benzotriazolium iodide ([MeOcBtu]I) and 1-octyl-3-methyl-benzotriazolium bis (trifluoromethanesulfonyl) imide ([MeOcBtu]TF2N) were successfully synthesized and analyzed by FTIR, 1H-NMR and 13C-NMR. Extraction processes were conducted in various organic solvents, pH, and extraction time without/ with ionic liquids addition. The data of ratio between 99mTc distribution coefficient compared to Mo distribution coefficient showed that the addition of ionic liquids exhibited significant improvement of separation factor. The separation factor of extraction using conventional water immiscible solvent ranged between 0 – 8 and increased to 30 – 600 as ILs were added. The optimum conditions which achieved highest separation factor were pH 14 using [MeOcBtu]I-chloroform. Benzotriazolium-based ionic liquid potential to be developed as extractant in the separation of 99mTc from 99Mo. Keywords: Ionic liquids, benzotriazolium, technetium-99m, molybdenum, liquid-liquid extraction.

Abstract

Desa Malaka, Kabupaten Lombok Utara merupakan salah satu wilayah dengan permasalahan penyakit yang dominan berupa keluhan penyakit kulit dan hipertensi yang belum tertangani secara optimal. Selain itu, anak-anak usia sekolah dasar juga belum terbiasa menjalankan Perilaku Hidup Bersih dan Sehat (PHBS) dalam kehidupan sehari-hari. Kegiatan pengabdian ini bertujuan untuk meningkatkan kesadaran kesehatan masyarakat melalui dua pendekatan, yakni penyuluhan PHBS kepada siswa SD dan pemeriksaan kesehatan dasar kepada masyarakat umum. Kegiatan dilaksanakan di SDN 1 Malaka dan Dusun Kecinan. Edukasi dilakukan dengan metode penyuluhan dan demonstrasi praktek cuci tangan, sedangkan pemeriksaan kesehatan mencakup pengukuran antropometri, tekanan darah, gula darah sewaktu dan konsultasi keluhan umum. Hasil kegiatan menunjukkan bahwa mayoritas siswa memiliki kebiasaan PHBS yang baik, sedangkan sebagian besar masyarakat mengeluhkan penyakit kulit dan menunjukkan gejala hipertensi. Kegiatan ini terbukti bermanfaat sebagai upaya promotif dan preventif kesehatan masyarakat di daerah pesisir.
