WebApr 15, 2024 · The degradation of phenol at different concentrations by three strains was investigated at low temperature [Fig. 1 (b)]. At the degradation of 100 mg L −1 phenol, the degradation rate of Ju-A4 was 100% in 20 h, with a maximum degradation rate of 8.53 mg h −1. The degradation rates of Ju-A1 and Ju-A6 were 48.5% and 42.4% at 20 h. WebPhenol is moderately soluble in water - about 8 g of phenol will dissolve in 100 g of water. If you try to dissolve more than this, you get two layers of liquid. The top layer is a solution of phenol in water, and the bottom one a solution of water in phenol. The solubility behaviour of phenol and water is complicated, and beyond UK A level.
