| Abstract: | Trioctylamine is used to extract and separate interference ions The Cu(Ⅱ) 5 Br PADAP OP coloured system is used to determine micro copper in heavy oil The determining conditions of this method and the conditions of extraction and separation from interference ions with trioctylamine are inspected The extraction recovery of synthetic sample is 101 1% The relative standard deviation of analytical results for oil samples is less than 5 0% The apparent molar absorptivity is 1 02×10 5L/mol·cm |
