微量硼是海水的重要分析项目之一,目前以姜黄素比色法为最普遍。该法优点是灵敏度高,通常取0.5——1毫升样品即可。该法的缺点是试剂体积(Vr)加上水的体积(Vw)与样品体积(Vs)之比((V_r+V_w)/(V_3))相当大(例如,30/0.5和>57.5/1),而试剂和水中都有痕量硼(蒸馏水和去离子水中的硼量约为0.1微克/10毫升)。虽然在测定样品 Trace boron is one of the important analytical items of seawater, and curcumin colorimetric method is the most common. Advantages of the method is the high sensitivity, usually take 0.5-1ml sample can be. A disadvantage of this method is that the volume of reagent (Vr) plus the ratio of water volume (Vw) to sample volume (Vs) ((V_r + V_w) / (V_3) ), While traces of boron are present in both reagent and water (approximately 0.1 μg / 10 ml of boron in distilled and deionized water). Although the sample was measured
