石油的开采和运输过程中时常伴随着石油的泄漏和污染，当前矿物油的泄漏问题日益严重，已经引起了人们的高度关注。水中油类物质会破坏水体的生态平衡，漂浮在水面以油膜形式存在的油会影响空气和水的气体交换，危害水生物的生存。分散于水中以乳化状态存在的油被微生物分解时，将消耗水中的溶氧，容易使水质进一步恶化。因此，对于水中油类污染物含量的检测显得尤为重要。水中油类物质含量的在线检测是一个技术难题，目前水中油的检测技术以红外分光光度法、紫外荧光法和气相色谱法为主，难以满足水中油在线检测的要求。本文提出了一种新型的水中油类物质含量的在线检测方法，创造性地将颗粒光散射技术引入到水中含油量的在线分析领域。通过分析油滴颗粒在空间中的光散射分布，建立了散射信号与含油量之间的相关关系，实验证明，光散射法与红外分光光度法测定的结果一致，相关系数R2＞0.98。光散射法具有快速、无污染的优点，可用于海洋、河流等水体中油类污染的在线检测。
