dc.description.abstractKarbon aktif banyak digunakan sebagai adsorben karena kemampuannya mengadsorspsi. Salah satu pemanfaatan karbon aktif ialah sebagai pembersih udara pada sistem tata udara reaktor nuklir untuk mengadsorpsi radioaktif I-131. Radioaktif ini berbahaya bagi makhluk hidup dan lingkungan. Penelitian ini bertujuan menguji efisiensi adsorpsi karbon aktif terimpregnasi trietilenadiamina (TEDA) terhadap I-131. Karbon aktif disintesis menggunakan metode aktivasi kimia dan fisika. Aktivator yang digunakan ialah H3PO4 3 M dan Na2CO3 5% b/v. Aktivasi fisika menggunakan suhu tinggi 700, 800, dan 900 °C. TEDA diimpregnasi ke dalam karbon aktif dengan cara perendaman dan pemanasan pada suhu 170 °C selama 3 jam. Karbon aktif terbaik ialah hasil karbonisasi 400 °C, aktivator kimia H3PO4 3 M dan pemanasan suhu tinggi 900 °C. Kadar air karbon aktif terbaik ialah 0,43%, bilangan iodin 137,47 mg/g, dan luas permukaan 378,24 m2 /g. Karbon aktif ini kemudian diimpregnasi menggunakan TEDA 5% b/b dan 8% b/b. Hasil adsorpsi terhadap I-131 karbon aktif tanpa impregnasi, impregnasi 5% TEDA dan 8% TEDA berturut-turut ialah 40,78; 35,89; dan 32,00 %.id
dc.description.abstractActivated carbon is widely used as an adsorbent due to its adsorbent ability. One of the uses of activated carbon is as an air purifier in the air system of a nuclear reactor to adsorb radioactive I-131. This radioactive is harmful to living things and the environment. This study aims to test the adsorption efficiency of triethylenediamine (TEDA) impregnated activated carbon against I-131. Activated carbon is synthesized using chemical and physical activation methods. The activators used are H3PO4 3 M and Na2CO3 5% w/v. Physics activation uses high temperatures of 700, 800, and 900 °C. TEDA is impregnated into activated carbon by immersion and heating at 170 °C for 3 hours. The best activated carbon is the result of carbonization of 400 °C, chemical activator H3PO4 3 M and high temperature heating of 900 °C. The best activated carbon water content is 0,43%, iodine number is 137,47 mg/g, and surface area is 378,24 m2 /g. This activated carbon is then impregnated using a TEDA of 5% w/w and 8% w/w. The adsorption result of I-131 activated carbon without impregnation, impregnation of 5% TEDA and 8% TEDA respectively was 40,78; 35,89; and 32,00%.id
