Abstract

We report on the synthesis of lead(II) carbonate-containing nanoparticles using the polyol process under high-energy ultrasound or microwave irradiation as alternate energization methods. Five carbonate source precursors are used in the reaction, and the precipitation reactions generate four different crystal products, depending on the precursor. More alkaline precursors produce the hydroxy-carbonate structures (abellaite, or its potassium analog, and hydrocerussite), while the less alkaline precursors produce the simple carbonate structure (cerussite). Ultrasonication or microwave irradiation during the arrested precipitation ensures the formation of nanoparticles <100 nm in diameter in a mostly single crystalline phase in all cases, bar one. The products were characterized by powder X-ray diffraction, dynamic light scattering, electron microscopy, infrared spectroscopy, and thermal analysis. These nanoparticles are targeted as X-ray contrast agents for biological imaging, particularly of fine vasculature where small particle size is essential.

摘要

我们报道了在高能超声或微波辐射作为替代激发方法的条件下,采用多元醇法合成含碳酸铅(II)的纳米颗粒。反应中使用了五种碳酸盐源前驱体,根据前驱体的不同,沉淀反应会生成四种不同的晶体产物。碱性更强的前驱体生成羟基碳酸盐结构(白铅矿或其钾类似物以及碳酸铅矿),而碱性较弱的前驱体生成简单的碳酸盐结构(铅白)。在停止沉淀过程中进行超声处理或微波辐射可确保在所有情况下(有一种情况除外)形成直径小于100 nm的纳米颗粒,且大多为单晶相。通过粉末X射线衍射、动态光散射、电子显微镜、红外光谱和热分析对产物进行了表征。这些纳米颗粒被用作生物成像的X射线造影剂,特别是用于对小粒径至关重要的精细脉管系统成像。
