TY - JOUR ID - TI - Applications Of Home -Build Micro Flow Injection (μFIA) Spectrophotometric system for Chloride Determination in Water AU - YOUSIF SHAFI J. ALJORANI AU - AND K. H. AL-SOWDANI PY - 2020 VL - 46 IS - 1 SP - 195 EP - 205 JO - Journal of Basrah Researches (Sciences) مجلة ابحاث البصرة ( العلميات) SN - 18172695 2411524X AB - 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 labs- made 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.
