Analysis of formaldehyde in aqueous solutions by the enzymatic method
Języki publikacji
Abstrakty
A new sensitive analytical method was developed.The method enables guantitative analysis of formaldehyde ( up to 0.75 nmol per 1 cm3 reaction mixture) in agueous solutions and municipal sewage.For the purpose of the study,use was made of the non-cancerogenic chromogen,3,3' , 5,5' - tetramenthylobenzidine (TMB),which is oxidized by hydrogen peroxide in the peroxidase reaction to form a dye (which can be determined by photometry).The objective of the present study was to examine the eficiency of the enzymatic kit ALCOTEST ( containing alcohol oxidase,peroxidase,chromogen and buffering components ) when used for the determination of formaldehyde in water solutions and municipal sewage.
