Abstract

We investigated samples of flint minerals from the lime deposits of Donetsk (gray flint) and Kamenets-Podolsk (black flint) regions of Ukraine by thermogravimetry and differential thermal analysis. Both minerals contain up to 1% of the organic phase. Bioassay of “silica water” was performed using two plant test organisms: onion Allium cepa (a monocotyledonous plant) and wheat Triticum vulgare grain; tap water infused with both black and gray flint stimulates the germination of onion roots and affects the length of the roots of wheat grain. The concentration of silicon is an essential factor in the stimulating effect of silica water on the development and growth of research plants. With a decrease in the flint particle size from d > 0.5 mm to d < 0.25 mm, the silicon concentration in tap water increases from 1.8 to 8.1 mg/dm³. There is a concentration dependence of the stimulating effect of the microelement on biological objects. The method of water purification with flint minerals can be practically implemented both under static conditions by infusing water with flint and under dynamic conditions by water filtration through columns packed with the mineral. The studies suggest the high biological activity of silicon in the aqueous medium, which creates a theoretical basis for the use of this mineral as a stimulator of the growth and development of plant organisms and may indicate the beneficial effect of silica water on living organisms.

用燧石矿物处理过的自来水的生物测定中的植物试验生物

摘要

我们通过热重分析和差热分析研究了来自乌克兰顿涅茨克（灰色燧石）和 Kamenets-Podolsk（黑色燧石）地区石灰矿床的燧石矿物样本。两种矿物质都含有高达 1% 的有机相。“二氧化硅水”的生物测定是使用两种植物测试生物进行的：洋葱洋葱（一种单子叶植物）和小麦小麦；注入黑色和灰色燧石的自来水会刺激洋葱根的发芽，并影响小麦籽粒根的长度。硅的浓度是硅水对研究植物发育和生长产生刺激作用的重要因素。随着燧石粒径从d > 0.5 mm减小到d< 0.25 mm，自来水中的硅浓度从 1.8 增加到 8.1 mg/dm ³。微量元素对生物物体的刺激作用存在浓度依赖性。使用燧石矿物净化水的方法可以在静态条件下通过向水中注入燧石和在动态条件下通过填充矿物的柱子过滤水来实际实施。研究表明，硅在水性介质中具有很高的生物活性，这为使用这种矿物质作为植物有机体生长和发育的刺激剂创造了理论基础，并可能表明二氧化硅水对生物体的有益作用。
