A simple photoelectric meter is described which allows the molybdenum blue formed in sea water, due to the presence of phosphate, to be estimated within that due to ± 0·25 mg. phosphate-P per m.3.The effects of concentration of acid, molybdate, reductant, temperature and suspended particles on the rate of formation, fading and amount of molybdenum blue, formed in sea waters containing phosphate are detailed.Intramolecular changes taking place during storage of molybdate solutions, and while being mixed with acidified sea water, have been investigated.The hydrolysis of organic phosphorus compounds in acidified sea water at 140° C , and the prevention of arsenate formation, are described.Procedures, resulting from these investigations, for the estimation of phosphate, and of total phosphorus, are described.The growth of bacteria and the physical adsorption of organic phosphorus compounds in solution on the walls of glass vessels used for storage of sea water have been investigated, and a method of prevention evolved.

海水中磷酸盐和总磷的估算

描述了一种简单的光电计，它允许由于磷酸盐的存在而在海水中形成的钼蓝估计在±0·25 mg 的范围内。每平方米磷酸盐-P。3详细介绍了酸、钼酸盐、还原剂、温度和悬浮颗粒的浓度对含磷酸盐的海水中形成的钼蓝的形成速度、褪色和数量的影响。钼酸盐溶液储存过程中发生的分子内变化，同时已经研究了与酸化海水混合的有机磷化合物。描述了在 140°C 下酸化海水中有机磷化合物的水解，以及防止砷酸盐的形成。从这些研究中得出的用于估算磷酸盐的程序，以及对细菌的生长和溶液中有机磷化合物在用于储存海水的玻璃容器壁上的物理吸附进行了研究，并提出了一种预防方法。
