1. Geochemical Investigation of Trace Metals in Crude Oils from Some Producing Oil Fields in Niger Delta, Nigeria

TEMPLE N CHIKWE; Mudiaga Onojake

Articles in Press, Accepted Manuscript, Available Online from 17 August 2021


  The concentrations of trace metals in crude oil samples obtained from eight producing fields from Niger Delta Nigeria were analyzed using a 700 model Perkin Elmer Atomic Absorption Spectrophotometer. Results showed the following ranges for the trace metals, Cu (0.01- 0.04 mg/kg); Fe (0.05 – 5.90 ...  Read More
