| Abstrak/Abstract | A study on adsorption of AFB1 in corn (kernelandgrained) on natural zeolite and bentonite has been investigated. The first work was adsorption in a batch system of standard AFB1 solution on adsorbents. Some factors such as contact time, concentration of AFB1 and particle size of adsorbent were evaluated. The amount of AFB1adsorbed was calculated based on the difference of AFB1concentration before and after adsorption determined by high performance liquid chromatography (HPLC) method. Adsorption of AFB1in corn sample was emphasized by mixing aqueous suspension of sample with adsorbent. Concentration of AFB1 in suspension was analyzed by enzyme-linked immuno-sorbent assay (ELISA) method. Result shows that adsorption of AFB1onadsorbents of natural zeolite and bentonite is very fast. Within 15 min 99% of AFB1 (200 ng/mL) has been adsorbedby 25 mg of bentonite and 96% by zeolite. The particle size higher than 200 mesh did not give significant effect onthe AFB1 adsorption capability. Effectiveness of zeolite in adsorbing AFB1 is lower than that of bentonite. Capabilityin reducing AFB1 contamination in corn samples (kernel and meal) for both adsorbents is lower than that in standard solution. |
