浮选组合药剂协同效应定量研究

应用浮选药剂理论和表面活性剂的物理化学性质，探索了浮选组合药剂的协同效应。以油酸和不同碳链长度的羧酸类捕收剂、油酸钠和不同饱和度的羧酸类捕收剂、乳化剂和油酸钠、磺酸盐类捕收剂和油酸钠、羧酸类捕收剂和苯甲羟肟酸等组合药剂为例，通过计算药剂结构参数和疏水链-疏水链之间相互作用，结合文献数据，发现2种药剂结构参数相差越大，组合后溶液的表面张力下降越大；疏水链之间相互作用较强的2种捕收剂，选择性好的与捕收能力强的组合，浮选效果一般较好。该研究结果对组合浮选药剂协同效应的定量研究具有理论参考意义。

Quantitative Research of Synergistic Effects of Combined Flotation Reagents

The synergistic effects of combined reagents have been investigated using the application of the flotation reagents theory and the physicochemical properties of surfactants. Taking some combined reagents such as oleic acid and carboxylic acid with different carbon chain length,sodium oleate and carboxylic acid with different saturation，emulsifier and sodium oleate，sulfonate and sodium oleate，carboxylic acid and benzohydroxamic acid，for example，through the calculation of agent structure parameters and interaction of hydrophobic chain/hydrophobic chain，and compared with literature data，it is found that the combined reagent with large difference in agent structure parameter，surface tension descending significantly，strong interaction of hydrophobic chain/hydrophobic chain，and strong selectivity and collecting ability performs better in flotation. This paper has theoretical refevences significance on quantitative research of combined reagents synergistic effects.
