| Abstract | ||
| The research includes the study of photodegradation to crash TB and RB dyes in their aqueous solutions of titanium dioxide using with a Uv lamp intensity 6 watts under normal conditions, at laboratory temperature. The effect of changing of the catalyst concentration of TiO2 and choose the best concentration. Find kinetics study included retail optical for dye and the results indicated that it kinetics of first class we calculate the activity energy for two dyes equal 42.82KJ/mol for RB and 33.21KJ/mol for TB and study the effect of concentration of the dye in different time periods in presence of TiO2/UV. The effect of temperature in the speed optical crash and remove the colour within the range of (36-45)°C and the results showed that high temperatures led to an increase in the rate of the destroy dyes. | ||
