Phenols are widely used in pharmaceuticals, dyes and indica­tors and as general disinfectants. They may occur in household and industrial wastewaters and in natural waters; they can also enter potable water supplies and chlorination of such waters results in malodorous chlorophenol products that are detectable from 0.001 mg/L (1 ppb). The HANNA colorimetric method determines phenol and all ortho and para substituted phenols. Since substitution generally lowers the response, the readable value obtained by this method is the minimum concentration of phenolic compounds present. Natural water usually contains less than 0.001 mg/L (ppb) of phenols, but sometimes values up to 0.02 mg/L (20 ppb) also occur.
Since the concentration of phenols in wastewater is generally subjected to biological and chemical degradation, preserve samples in the refrigerator and analyze within 4 hours after collection.
Note:
mg/L is equivalent to ppm (parts per million), ppb are
parts per billion.
Phenolic compounds react to form a yellow to orange dye with 4-amino antipyrine in alkaline solution buffered at pH about
10. The absorbance of this colored product is proportional to the concentration of phenols present in the aqueous sample.

• Fill each glass vial with 10 mL of sample, up to the mark.
• Insert one of them into the left hand opening of the checker disc. This is the blank.
• Add to the other glass vial 1 packet of HI 3864A-0 Re­agent. Replace the cap and mix.
• Add 1 packet of HI 3864B-0 Reagent.
• Start the waiting time of 10 minutes. Replace the cap and shake the vial until the powder has totally dis­solved. The solution will turn a color yellow to or­ange. This is the reacted sample.
• Remove the cap and in­sert the reacted sample into the right hand open­ing of the checker disc.
• Hold the checker disc so that a light source illuminates the samples from the top.
• After the 10 minutes have passed, rotate the disc while looking at the color test windows and stop when you find the color match. Read
10 mL
the value in the result window and record it in mg/L (or ppm) of Phenols.
• If the color of the sample is too intense to make a color match with the mirror installed, then remove from the checker disc:
i. the glass vials ii. the LR disc iii. the mirror and its holder.
• Install the HR (0.5÷5 mg/ L) disc and replace the glass vials in the checker disc.
• Hold the checker disc so that a light source illuminates the samples from the back windows.
• Rotate the disc while looking at the color test windows and stop when you find the color match. Read the value in the result window and record it in mg/L (or ppm) of Phenols.
For best results: Intensely colored samples will make the color
matching determination difficult and they should be adequately treated before performing the test. Sus­pended matter in large amounts should be removed by prior filtration.
Caution: Ultraviolet radiation may cause fading of colors.
When not in use, keep the disc protected from light, in a cool and dry place.
