在本文中研究了在三乙烯四胺存在下钪-铬天青S-十二烷基硫酸钠(SLS)的成络反应,进行了人工合成样品镧中钪、钇中钪的测定,结果满意。根据反应现象,对络合物的成因提出一点看法。实验部分一、主要试剂及仪器 1.钪标准溶液:含氧化钪(Sc_2O_3)1.000毫克/毫升的酸性溶液;10微克/毫升溶液由此溶液稀释而成。 2.铬天青S(CAS):1×10~(-3)M水溶液。 3.十二烷基硫酸钠(SLS):1×10~(-3)M水溶液。
In this paper, the complex reaction of scandium-chromium azure S-sodium lauryl sulfate (SLS) in the presence of triethylenetetramine was studied. The determination of scandium and yttrium scandium in lanthanum samples was carried out. The results were satisfactory . According to the reaction phenomenon, the origin of the complex made a point. Experimental part A, the main reagents and equipment 1 scandium standard solution: scandium oxide (Sc_2O_3) 1.000 mg / ml of acidic solution; 10 micrograms / ml solution from the solution diluted. 2. Chromium Azure S (CAS): 1 × 10 ~ (-3) M aqueous solution. 3. Sodium lauryl sulfate (SLS): 1 × 10 -3 M aqueous solution.
