Methyl hydrazine and hydrazine hydrate in reaction mixtures from the preparation of methyl hydrazine were determined by Gas Chromatography. 建立了甲基肼合成液中甲基肼、水合肼含量的气相色谱分析方法。
The modified method of improving the interface absorbing of natural manganic ore by sulphuric acid and hydrazine hydrate was studied. The result shows that the adsorbing of natural manganic ore to methyl orange is improved markedly after it is modified by sulphuric acid and hydrazine hydrate; 研究了利用硫酸和水合肼提高天然锰矿界面吸附能力的改性方法,结果表明:天然锰矿经硫酸和水合肼反应改性后,对甲基橙的吸附能力明显提高。
