The invention discloses a method for measuring seawater chemical oxygen demand by photometry, wherein the seawater exemplar is first pre-processed, then using the basic potassium hypermanganate as reaction system, the potassium permanganate is deacidized quantitatively by organics to produce manganate, using pure water or margin solution as reference ratio, measuring the absorbance an of the manganate at its maximum absorbing wave length 430 nm, drafting the A-COD value operating curve, obtaining the concentration of the organics in the water, i.e.

本发明公开了一种对海水化学需氧量进行测定的光度测定法，该方法首先将海水样品进行预处理，再以碱性高锰酸钾为反应体系，这样海水中的有机物在强碱性介质中与过量的高锰酸钾迅速反应，高锰酸钾被有机物定量还原后生成锰酸盐，以纯水或空白溶液作参比，在锰酸盐的最大吸收波长430nm处测其吸光度A，该吸光度A与海水样品中的有机物的含量具有正相关关系。
