本研究對石英及高嶺土、滑石之黏土礦物進行等溫吸附，實驗結果顯示出吸附量與比表面積存在一正比關係；其中，比表面積最低之石英，吸附密度及吸附量均呈現出較低的數值。石英及滑石之表面性質也藉由對PEO的凝聚作用來探討，增加pH值會提高石英對水的親和力，水會取代PEO之醚氧基與石英表面之氫氧根作用且產生氫鍵。增加溶液離子強度也會因電雙層壓縮而增強石英的凝聚效果。另外，降低pH值及改變離子強度均能使滑石對PEO凝聚效果增加，但由於高百分比之固體沉降使膠羽粒子會團聚在一起；造成沉降速率變慢。
石英對PEO吸附之FTIR也在本研究中被探討；因吸附密度值偏低而無法顯示出PEO與石英鍵結之氫鍵。水庫淤泥對PEO的凝聚作用顯示出，隨著固含量增加，PEO的添加劑量越少。最後則是淤泥礦漿的選擇性分離，淤泥漿料經過凝聚作用後，上層懸浮液所含之石英量較少，證石英在水庫淤泥中的凝聚作用有優先沉降的效果。

This research study the isothermal adsorption of PEO on quartz and various clay minerals such as kaolinite and talc. Results indicated that the amount of PEO adsorption exists a postive correlation with the specific area of adsorbent. For example, quartz possessing the lowest specific surface area has the lowest amount of PEO adsorption. The surface characteristics of adosobent before and after PEO adsorption were discussed by flocculation tests. Increasing the pH of solution would increase the affinity between water molecules and quartz surface. Water molecules would replace PEO inteacting with quartz surface by hydrogen bonding. Increasing ionic strength of solution led to a increase in flocculation of adsoebents by compressing the electrical double layer. On the other hand, both lowering the pH value and increasing the ionic strength of solution could enchance the flocculation of PEO on talc. In general PEO flocculation produce less compacted aggregated with a slow settling rate.
The FTIR spectrum of the PEO loaded quartz was also investigated in the study. Because of the low density of adsorption, FTIR could not reveal the hydrogen bond between PEO and quartz. The result of the adsorption of PEO on reservoir sediments indicated that the PEO dosage required for flocculation decreases with increasing solid content of reservoir sediments in slurry. Finally, the selective flocculation of PEO on quartz in the slurry of reservoir sediments results in a concentration of quartz on the bottom layer after flocculation with PEO.
