Applications of home-build micro flow injection (μFIA)‎ spectrophotometric system for chloride determination in water

Abstract EN

A home-build micro flow injection analysis (µFIA) was constructed and used for chloride ion detection in natural and freshwater samples which were collected from Shatt al-Arab river and the Basrah city- south of Iraq.

Two lmade microcontroller software programs were designed.

The first program, type UNO used to control the lab- made mini peristaltic pump to propel the chemicals reagents to detector.

While, the other program was Mega type which was employed as a data-logger to manipulate and recording the response as peak height corresponding the concentration by using Microsoft Excel 2010 program.

The linearity, regression coefficient for seven points, detection limit and % R.

S.

D for ten replicates of 25 μg/ml were 5-35 μg/ml, 0.9984, 0.5 μg/ml and 0.0597 % respectively.

The sample throughput was 120 samples per hour.

so each one sample consumed 94.2µL of chemical reagents and 120 samples consumed 11.30ml of chemical reagents.

The home build semi-automated micro-flow injection analysis (µFIA) system was applied successfully for chloride estimation with simple manifold, high sensitive and accurate.
