研究了油酸钠对碳酸钙附聚的影响。油酸通过红外光谱法测定。为了检测吸附在碳酸钙晶体上的油酸酯的量，使用差热分析方法。研究了附聚物尺寸和zeta电位随油酸钠浓度和pH值的变化。发现吸附在碳酸钙上的油酸钠的量不仅取决于浓度，还取决于pH值和zeta电位。结果还表明，在选定的实验条件下，达到最大油酸钠吸附的临界油酸钠浓度约为300 ppm。（© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA，魏因海姆）
The effect of Na‐Oleate on the agglomeration of calcium carbonate was investigated. Oleate is determined by Infrared spectroscopy. In order to detect the amount of Oleate adsorbed on the calcium carbonate crystals, the differential thermal analysis method was used. The agglomerate size and zeta potential were investigated as a function of Na‐Oleate concentration and pH value. It was found that the amount of Na‐Oleate adsorbed on the calcium carbonate is not only depending on the concentration but also on the pH value and zeta potential. The results also show that the critical Na‐Oleate concentration, where the maximum Na‐Oleate adsorption was reached, was found approximately 300 ppm under the selected experimental condition.
