WebGlobal Research online WebJan 13, 2024 · Phenols are widely used in industries despite their toxicity, which requires governments to limit their concentration in water to 5 mg/L before discharge to the city sewer. Thus, it is essential to develop a rapid, simple, and low-cost detection method for phenol. This study explored two pathways of peroxidase immobilization to develop a …
Web(insoluble in water) in phenol raises the upper CST of phenol-water system by about 300. Substances which are soluble in both the liquids tend to lower the upper CST and raise the lower CST. For example, sodium oleate is soluble in both water and phenol. Addition of 1% solution of sodium oleate to phenol-water system lowers the CST value by 450.
