Abstract:

 

A new method for determining ternary mixtures of vitamin  B1,  B6  and B12  using second derivative   spectrophotometry is described. The procedure is accurate,   nondestructive and does not require any separation step or the   solving of equations. Calibration graphs were linear up to 20  m   gml-1  of vitamin B1  at 228.9 nm (r=0.9999),   vitamin B6  at 309.6 nm (r=0.9999) and vitamin B12  at   361.7 nm (r=0.9998). The method was successfully applied for analyzing   synthetic mixtures and commercial pharmaceutical preparations.
