Abstract

The aim of research is to develop the electrospun fibers for cyanide detection based on ninhydrin and acidic hydrolysis reaction. The fibers were prepared by sol-gel method and then formation fibers with electrospinning method. A high voltage of 15 kV, the distance between the needle tip and collector of 15 cm and flow rate of 1 mL h–1 were used for electrospinning method. The optimum conditions for cyanide detection were used 25 wt% ninhydrin concentration, 3 wt% mesoporous silica concentration and contact time 5 mins. The fibers were investigated the performance quantities the cyanide detection by spectrophotometry at wavelength 480 nm. The detection limit of the cyanide test strip was found in mg L–1 level. Consequently, fibers were applied to waste water from cassava fermentation compare with batch analysis. The results showed that no detection the cyanide was observed in the sample. The electrospun fibers test strip can be detected cyanide with pre-screening test and suitable for selective choice in cyanide detection in waste water.
