Gemini surfactants with different alkyl chain lengths, [C₁₆H₃₃N⁺ (CH₃)₂CH₂]₂•2Br⁻ (G_16-2-16), [C₁₂H₂₅N⁺ (CH₃)₂CH₂]₂•2Br⁻ (G_12-2-12), and [C₈H₁₇N⁺ (CH₃)₂CH₂]₂•2Br⁻ (G_8-2-8), were applied to modify Silica nanosheets (SiNSs). FT-IR, XRD, TG, SEM, TEM, BET and Zeta potentials were carried out to study the surface and structure of the resultant organo silica nanosheets (organo-SiNSs). The loading amounts of G_16-2-16, G_12-2-12, and G_8-2-8 were 0.23, 0.14, and 0.09 mmol for 1 g SiNSs, respectively, suggesting the increased length of the alkyl chain promoted the modification process. Organo-SiNSs exhibited rapid adsorption property (within 5 min) and high adsorption capacity (64.19 mg g⁻¹) toward ibuprofen (IBP) at such a low surfactant concentration (0.42 mmol for 1 g SiNSs), and can be regenerated at least for 3 cycles. Furthermore, the longer the alkyl chain, the more IBP removed, the adsorption capacities of three organo-SiNSs decreased in the order G_16-2-16-SiNSs (64.19 mg g⁻¹) > G_12-2-12-SiNSs (40.14 mg g⁻¹) > G_8-2-8-SiNSs (4.84 mg g⁻¹). Moreover, electrostatic interaction as well as the partition effect plays an important role in the adsorption. Based on the fast adsorption and cost-effective feature, organo-SiNSs were further proved to be outstanding adsorbents for specific organics removal.

双子表面活性剂具有不同的烷基链长，[C ₁₆ H ^ ₃₃ Ñ ⁺（CH ₃）₂ CH ₂ ] ₂ •2BR ^-（G _16-2-16），[C ₁₂ H ^ ₂₅ Ñ ⁺（CH ₃）₂ CH ₂ ] ₂ •2BR ^-（G _12-2-12），和[C ₈ H ^ ₁₇ ñ ⁺（CH ₃）₂ CH ₂ ] ₂ •2BR ^-（G_8-2-8）被用于改性二氧化硅纳米片（SiNSs）。进行了FT-IR，XRD，TG，SEM，TEM，BET和Zeta电位研究了所得有机硅纳米片（organic-SiNSs）的表面和结构。1 g SiNS的G _16-2-16，G _12-2-12和G _8-2-8的负载量分别为_0.23、0.14和0.09 mmol，这表明增加的烷基链长度促进了SNS的负载。修改过程。有机SiNSs具有快速吸附性能（5分钟内）和高吸附容量（64.19 mg g ^-1））在如此低的表面活性剂浓度下（1 g SiNSs为0.42 mmol）向布洛芬（IBP）迁移，并且至少可以再生3个循环。此外，烷基链越长，除去的IBP越多，三种有机-SiNS的吸附能力按G _16-2-16 -SiNSs（64.19 mg g ^-1）> G _12-2-12 -SiNSs（ 40.14 mg g ^-1）> G _8-2-8 -SiNSs（4.84 mg g ^-1）。而且，静电相互作用以及分配效应在吸附中起重要作用。基于快速吸附和具有成本效益的特点，有机-SiNS被进一步证明是去除特定有机物的杰出吸附剂。
