In this study, the effect of particulate matter type, temperature, oil type and weathering degree on the interaction between dispersed crude oil droplets and particulate matter was investigated. The increase of total petroleum hydrocarbon (TPH) percentage in oil–particle aggregates (OPAs) could be attributed to the increase of oil polarity or viscosity. For small size particulate matter, there was a fine dependence relationship between the TPH percentage in OPAs and the oil viscosity and the content of polar components, respectively (R² > 0.7502). And the total organic carbon content also played an important role in the formation of OPAs. The petroleum hydrocarbon extracts of OPAs showed a decrease in short-carbon-chain components and a relative increase in long-carbon-chain compounds. Petroleum hydrocarbon compounds trapped by three types of particulate matter exhibited a similar change tendency, but there was no apparent difference in the residual TPH percentage in water.

分散的原油液滴与颗粒物之间的相互作用。

在这项研究中，研究了颗粒物类型，温度，油类和风化程度对分散的原油液滴与颗粒物之间相互作用的影响。油颗粒聚集体（OPA）中总石油烃（TPH）百分比的增加可能归因于油极性或粘度的增加。对于小颗粒物，OPA中的TPH百分比与油的粘度和极性成分的含量之间存在良好的依存关系（R ²> 0.7502）。总有机碳含量在OPAs的形成中也起着重要作用。OPA的石油烃提取物显示出短碳链成分减少，而长碳链化合物相对增加。被三种类型的颗粒物捕集的石油碳氢化合物表现出相似的变化趋势，但水中的残留TPH百分比没有明显差异。
