Open publisher page 0 citations

Abstract

By use of single sweep polarography in 50% N,N dimethylformamide and ammonia ammonium chloride medium, a second derivative polarographic wave which has a good shape is observed for naphthalene The peak potential is about -1 05v(vs SCE) In this test condition, the concentration of naphthalene is linear with peak current in the range of 5 00×10 -6 M to 5 00×10 -4 M, the detection limit is 5 00×10 -6 M This method can be used to determine naphthalene content of the enviromental sample such as coal, mothball and asphaltic bitumen
