Refractories containing carbon-Determination of magnesium oxide content-CyDTA volumetric method
GB/T13246-1991含碳耐火材料化学分析方法CyDTA容量法测定氧化镁量
With adding a little of CYDTA.
由于在底液中加入了少量的CYDTA。
According to the mechanism of stabilizing agent and the reported stabilizing agents, we selected CyDTA as the stabilizing agent to prepare Pd/C catalyst.
根据纳米粒子合成过程中稳定剂的作用机理和已知报道的稳定剂，我们筛选CyDTA作为合成Pd/C催化剂的稳定剂。
Uranium solution is obtained electrolytically by reducing uranyl ion on mercury cathode. The effect of the addition of various aminopolycarboxylic acids (such as EDTA, DTPA, CyDTA and TTHA) and organic water-miscible solvents (such as CH3OH, C2H5OH and CH3COCH3) on the stability of ura-nium in air has been investigated. The absorption spectra of uraniumand uraniumin 1 mol/l and 9mol/l hydrochloric acid solutions are examined.
本文采用汞阴极电解还原法制备了铀溶液，研究了在盐酸介质中各种氨羧络合剂乙二胺四乙酸二钠、二乙三胺五乙酸、1，2-环已烷二胺四乙酸、三乙基四胺六乙酸和水溶性有机溶剂甲醇、乙醇和丙酮的存在对铀稳定性影响，测定了在不同盐酸浓度中铀和铀的吸收光谱。
