In this work, a simple electrical conductivity measurement technique is applied to effectively determine the boron concentration in the aqueous solution based on the ionized complex formed between boron species and vitamin B6, which can be easily detected and accurately measured using a conductivity meter. The log of boron concentration is linearly correlated with the log of conductivity change within the range of 0–550 mg/L boron content. The correlation coefficient (R2) is up to 0.99882. The reproducibility is 100%. The methods can be directly applicable in deionization water or diluted seawater within diluted factor 34 times or higher (0–1600 us/cm conductivity range). This work provides a cost-effective technology for the boron measurement and will be of great industrial importance in boron measurement field.
