Pollution hazards can be overcome by knowing the pollution status of the location. Minerals of Fe are most found in sediments. We used to monitor and assess of Fe using microwave optimized BCR. In an optimized leaching process, the variations of the size of the sediment particles, pH, and concentration of solvents in the oxidation fraction were analyzed to find the maximum assessment. The samples were tested by XRD and then leached Fe by optimized microwave BCR method to apply of 100 and 200 mesh of sample-accurate and precision. Fe concentration in sediments was recorded of 200 mesh more higher comparing those in 100 mesh. Concentrations of 0.5 M NH2OH.HCl with pH 1.5 was 1.5 times higher compared to other treated concentrations. The amount of Fe in the location of the Pasir Putih was still below the threshold, indicating no pollution in the waters of Pasir Putih Beach. © 2020 Author(s).
