Abstract

The sol–gel method is used for the synthesis of silica nano particles from Saccharum munja plant. Dried Saccharum munja plant was heated at 600 °C for 4 h to convert into Saccharum munja ash (SMA). By solution of sodium hydroxide, silica was extracted from the ash of Saccharum munja along with the sodium silicate. Silica was precipitated by H₂SO₄ at pH 4, sodium dodecyl sulfate and cetyl-tri-methyl-ammonium bromide were used as a surfactants and water/butanol were taken in same ratio. Different parameters like aging temperature, time, surface coverage and the effect of surfactant are tested to identify the favorable conditions for producing the homogeneous mixture of silica nanoparticles. X-ray diffraction and scanning electron microscopy data reveal that silica nanoparticles are amorphous and have size in the range of 30–50 nm. The results obtained by this method show the economic importance of the Saccharum munja.

溶胶-凝胶法可用于从糖蔗植物中合成二氧化硅纳米颗粒。将干燥的蔗糖忍者植物在600°C下加热4小时，以转化为蔗糖忍者灰（SMA）。通过氢氧化钠溶液，与硅酸钠一起从蔗糖的灰分中提取二氧化硅。H ₂ SO ₄沉淀二氧化硅在pH 4下，十二烷基硫酸钠和十六烷基三甲基溴化铵用作表面活性剂，水/丁醇的比例相同。测试了不同的参数，如老化温度，时间，表面覆盖率和表面活性剂的作用，以确定用于生产二氧化硅纳米颗粒均匀混合物的有利条件。X射线衍射和扫描电子显微镜数据表明，二氧化硅纳米粒子是无定形的，尺寸在30–50 nm范围内。通过这种方法获得的结果表明了蔗糖的经济重要性。
