Boron determination in natural waters with curcumin using 2, 2‐dimethyl‐1, 3‐hexanediol to eliminate interferences |
| |
| Abstract: | Abstract This method meets the demands for a sensible and quick method for boron analysis in the field. The water sample is extracted with an equal amount of methyl‐isobutylketon (MIBK) containing curcumin and diol. After extraction and phase separation the aqueous phase is discarded and a mixture of sulfuric acid and acetic acid is added to the remaining MIBK. Boron and curcumin react to give the intensely redcoloured product rosocyanin. Water elimination procedures are not necessary. There are practically no interferences apart from the contamination from glass ware. |
