“…However, the mobile courts in Bangladesh have been detecting formaldehyde by the instrument namely Formaldehyde Meter Z-300 (Environmental Sensors Co, USA) with limited applications to food items. 6 Besides, formaldehyde can be quantitatively analyzed by spectrophotometry and fluorometry 19 , sol-gel based sensor 20 , flow-injection solid phase spectrophotometry 21 , HPLC 22 , and potentiometric sensors 23 . After reviewing the articles inquisitively, we aimed to develop a RP-HPLC method to analyze formaldehyde quantitatively in the dairy products which will be easier, more sensitive, more accurate as well as time and cost effective.…”

“…Bondioli e Della Bella 16 apresentaram um procedimento baseado na oxidação do glicerol por periodato, produzindo formaldeído, seguido da reação com acetilacetona (2,4-pentadinodiona) e posterior monitoramento do produto por espectrofotometria em 410 nm. Esta última reação trata de uma adaptação de procedimentos usuais para a determinação fluorimétrica e/ou espectrofotométrica de formaldeído, largamente empregados para análises de amostras ambientais [40][41][42][43] , bebidas 44,45 e outros biocombustíveis, como etanol 46 .…”
