Abstract

Nowadays harmful bloom tides affect greatly the economy of coastal states. For this reason, the present communication reports on a practical method for synthesizing SiO₂ and γ-alumina nanospheres, immobilized by sonochemistry on low-density porous foams and perlite granules, as a solution to this problem. A biostatic AgNP effect was incorporated into both materials, achieving AgSi and AgAl. The green-tide inactivation was performed by using Tetraselmis suecica under aqueous conditions. AgAl/FWGS displayed the best inactivation efficiency performance (94 %). Additionally, foams have significant buoyancy and are easy to handle, being an option for T. suecica inactivation for their easy recovering.

在低密度多孔材料上使用 Ag/SiO2 和 Ag/Al2O3 涂层灭活有害绿潮

如今，有害的海潮对沿海国家的经济造成了极大的影响。为此，本研究报告介绍了一种实用的方法，即通过声化学法在低密度多孔泡沫和珍珠岩颗粒上固定合成二氧化硅和γ-氧化铝纳米球，以解决这一问题。在这两种材料中都加入了具有生物静电效应的 AgNP，从而实现了 AgSi 和 AgAl 的效果。在水质条件下，使用 Tetraselmis suecica 进行了绿潮灭活试验。AgAl/FWGS 的灭活效率最高（94%）。此外，泡沫具有明显的浮力且易于处理，因其易于回收而成为灭活绿潮虫的一种选择。
