<jats:p>To solve the problems in the calibration of polyaromatic hydrocarbons sensor used in seawater, we proposed a new method that using 1,5-Naphthalenedisulfonic acid, disodium salt dihydrate instead of polyaromatic hydrocarbons standard substances to calibrate seawater polyaromatic hydrocarbons sensor. Relative to polyaromatic hydrocarbons standard substances, 1,5-Naphthalenedisulfonic acid, disodium salt dihydrate shows higher solubility in seawater, better stability under the detection wavelength of polyaromatic hydrocarbons and lower toxicity to organisms. Our results showed that the relative errors between real concentrations of standard substances and measuring concentrations of these standard substances via 1,5-Naphthalenedisulfonic acid, disodium salt dihydrate-calibrated sensor varied from 5~15%. Our method can reduce the complexity of calibration procedures, and keep the accuracy and precision of sensors in the determination of polyaromatic hydrocarbons in seawater.</jats:p>
