“…Because of its ability to analyze several samples, a very quick response time, tiny sample size injection, and excellent accuracy (8) .A liquid sample must be injected into a carrier solution that is moving in a continuous to the detector that records continuously the changes in absorbance (9,10) .Low sample and reagent use, partial and repeatable development of the related processes, and other characteristics of flow analysis are inherent (11) .Phenol an aromatic organic molecule consisting of a hydroxyl functional group (-OH) .Phenolic derivative compounds widely present in the environment,are used to make dyes ,polymers,medicines,and other organic molecules.Skin absorption, inhalation, ingestion,and a number of other methods can all result in phenol poisoning.If people are exposed to high doses of phenol, they could die (12 ), Many methods have been reported in literature for estimating total phenolic compounds such as determination total phenolic compounds in tea samples by Flow injection analysis system (13) ,automatic method for the determination of Folin-Ciocalteu reducing capacity in food products (14) .Flow injection system successful and fast method after adding smart phone technology to the design .…”
