Cetyltrimethylammonium bromide (CTAB) and sodium dodecyl sulphate (SDS) were chosen to establish the role of ionic micelles on the morphology of cyanidin 3,5-di-O-glucoside (cyanin) assisted synthesis of zerovalent iron nanoparticles. Nucleation and growth process depends upon the presence of CTAB and SDS. CTAB exhibited catalytic sub-, post- and dilution-micellar effect for the nucleation and growth process of FeNPs formation in the present investigations. Nucleation process of FeNPs formation was inhibited in presence of SDS. The different role of SDS (inhibition) and CTAB (catalysis) micelles might be due to the strong electrostatic attraction and repulsion with Fe³⁺ ions and cyanin. The reduction rates of Fe³⁺ ions by cyanin were found to be 3.9 × 10⁻³, 10.2 × 10⁻³, and 2.6 × 10⁻³ s⁻¹ for aqueous, CTAB and SDS, respectively. Transmission electron microscopic images indicate that the FeNPs are roughly spherical and poly dispersed.

选择十六烷基三甲基溴化铵（CTAB）和十二烷基硫酸钠（SDS）来确定离子胶束在花青素3,5-二-O-葡萄糖苷（花青素）辅助合成的零价铁纳米粒子的形态上的作用。成核和生长过程取决于CTAB和SDS的存在。在本研究中，CTAB对FeNPs形成的成核和生长过程表现出催化的亚，后和稀释胶束效应。在SDS存在下，FeNPs形成的成核过程受到抑制。SDS（​​抑制）和CTAB（催化）胶束的不同作用可能是由于强烈的静电吸引和与Fe ³⁺离子和花青素的排斥。花青素对Fe ³⁺离子的还原率为3.9×10 ^-3水溶液，CTAB和SDS分别为10.2×10 ^-3和2.6×10 ^-3  s ^-1。透射电子显微镜图像表明，FeNPs大致呈球形，并呈多分散状态。
