Abstract
Activated carbon extracted from yellowfin tuna fishbone has been successfully fabricated and functioned as an iron (Fe) adsorbent through a direct water filtration scheme. Carbonization temperatures (600, 700 and 800 ^{o}C) were applied in the activated carbon extraction process to determine how much influence it had on the ability to absorb Fe in terms of its pore morphology characteristics. Tests with a Surface Area Analyzer (SAA) were carried out to review the nature of the formed surface pores. Fe absorption performance was analyzed using Atomic Absorption Spectrometry (AAS). The carbonization temperature of yellowfin tuna fishbone has implications for the pore characteristics of the activated carbon produced. The mean pore size, total pore volume and specific surface area of activated carbon with a carbonization temperature of 600 ^{o}C were 5.7456 nm, 0.1896 cc/g, and 74.036 m^{2}/g, respectively. Each of these values decreased, except for the average pore size which increased when the carbonization temperature was increased to 800 ^{o}C. An analysis of what factors might trigger this phenomenon has also been reviewed in detail. In addition, the carbonization temperature also had an effect on the adsorption performance of the Fe formed, where activated carbon with a carbonization temperature of 600 ^{o}C had the most optimum adsorption ability compared to the other two samples. Various factors can be associated in analyzing the effect of yellowfin tuna fishbone carbonization temperature on the adsorbent behavior.
