A new method for the determination of trace copper in water by flame atomic absorption spectrometry with cloud point extraction was developed 摘要本文研究了浊点萃取火焰原子吸收光谱法测定微量铜。
Non - ionic surface active agents obtained from ethylene oxide and ethylene oxide propylene oxide block copolymers . determination of cloud point 环氧乙烷型及环氧乙烷-环氧丙烷嵌段聚合型非离子表面活性剂浊点的测定
Cloud point temperature at which a moticeable cloud of cloud of crystals or other solid material appears when a sample is cooled under prescribed conditions 浊点在规定条件下，当油样冷却至产生明显雾状的温度。 （产生雾状是由于有晶体形成或其他固定物质生成。 ）
