摘要
以TritonX 10 0为乳化剂将样品的甲基异丁基酮 二甲苯溶液乳化成乳浊液 ,以聚异丁烯空白溶液为参比 ,用标准加入法测定。建立了乳化技术 火焰原子吸收光谱法测定原油中铁、镍的快速分析方法。提出了配制空白溶液的原理及方法 ,对溶剂及乳化剂的选择、空白溶液的配制进行了考察 。
The methyl isobutyl ketone-dimethyl benzene solution of sample was emulsified into emulsion by emulsifier Triton X-100. The standard addition method was used to determine with polyisobutylene, emulsion as the reference. An analytical method for rapid determination of iron and nickel in crude oils by FAAS had been developed. A principle and method of preparing blank solution had been advanced. Choices of solvent and emulsifier, preparing blank solution were studied. The determination results were consistent with those obtained by ashing method-FAAS.
