The values are expressed the increase in temperature is able to promote the solubility of dispersed compounds. There are very few studies in the literature that observed the effect of UV irradiation and heat on turbidity. The results of our study are in accordance with these related studies previously conducted on UV irradiation and turbidity [36; 39; 40].
