Development of cost-effective inorganic arsenic extraction method for resource-limited regions: Analysis of efficiency and regulatory implications.

ABSTRACT: This study evaluated the effectiveness of coke and lemonade extraction methods compared to the standard 1 % v/v HNO₃ method for determining inorganic arsenic (iAs) concentrations in rice bran samples using a field-deployable method (Arsenator field kit). The limit of detection (LOD) for the methods was 45 μg kg^-1, comparable to existing literature. The extraction efficiencies were assessed by comparing iAs recovery rates, with coke extraction yielding the highest recovery of 127.4 %, followed by lemonade at 116.2 %, and HNO₃ at 100 %. Statistical analysis indicated strong correlations between the extraction methods, particularly between HNO₃ and coke (Pearson correlation coefficient, 0.990), suggesting that coke extraction is a reliable alternati
