Abstract
Tetraethyl lead TEL is an organometallic component that is added to gasoline to improve engine performance. This material is also called an anti-knock because it reduces the knocking of the engine. The engine starts to throttle if the oil in its pistons burns quickly or after a short period of time from entering it. In this study, a sensitive, simple, economical, fast and accurate, an indirect spectral analytical method has been developed using Eriochrome Black T as chelating agent without use of separation and isolation to estimate the amount of lead in the gasoline by using UV-Visible spectrophotometer instrument. The accuracy and sensitivity of the method were 99.9067 ± 0.09 and 0.0338 while the limits of detection (LOD) and qualification (LOQ) were 0.0721 and 0.2186 μg ml-1 respectively. The developed method can be applied to water, biological, environmental and fuel sample.
