Studies in photochromic behavior of some potassium hexacyanoferrate (II)‎–dye systems

الملخص EN

-The photochromic behavior of potassium hexacyanoferrate (II) – fuchsin basic and potassium hexacyanoferrate (II) – malachite green systems was investigated in detail.

The effect of variation of various parameters, like pH, light intensity, concentration of dyes, and concentration of potassium hexacyanoferrate(II), on the rates of forward and backward reactions of these systems has been observed.

Based on experimental data, a tentative mechanism has also been proposed.
