Results of zetapotential and FTIR measurements show that OL-4 is adsorbed on the surface of calamine principally by chemical reaction.
动电位和红外光谱测试结果表明，阴离子捕收剂OL-4在菱锌矿表面发生化学吸附；

The zetapotential of core-shell composite particles were still minus, so multiple layers of BFP on the surface of microspheres could be obtained.
真空干燥后的核壳复合粒子在不经任何表面修饰就可进行多层包裹BFP。

The results showed that the activation of sodium sulfide to the smithsonite due to the HS- ion adsorbed on the smithsonite's surface and lead to the zetapotential drop.
