Abstract

A research has been done on the influence of sulfuric acid activation on the performance ofbentonite as a cyanide biosensor. The concentration of sulfuric acid used was 0.5; 1; 1.5and 2 M. Activation with 2 M sulfuric acid resulted in an increase in surface area and basal spacing. The membrane biosensor made from 2M acid activated bentonite had better performance than the untreated bentonite membrane biosensor. A study on theeffect of membrane thickness on theperformance of the cyanide biosensor has also been conducted. The resultshowed that the performance of membrane which 5 mg/mL of thickness did not differ significantly.
