Arsenic, the tenth most prevalent element in the Earth’s crust, is known for its high toxicity and carcinogenic potential. Because of serious health risks associated with even low concentrations of arsenic in drinking water, the development of sensitive, accurate, and reliable detection methods is of critical importance. Hence, in the present review, comparative analysis of analytical lab and portable chemical methods of determination of water in arsenic are conducted, focusing on their accuracy, precision, detection limits, and practical applicability. The results demonstrate that analytical methods provide high accuracy and precision, while commercially available portable kits offer convenience and rapid results. Electrochemical sensors, particularly those modified with nanomaterials and other functional materials, show potential for on-site detection, with detection limits as low as 1 ppb. The electrode modifier, graphene oxide-gold nanoparticles composite, enhances the sensor's sensitivity and selectivity towards detection. Without disapproving any of the measurement techniques, the review offers appropriate details for the assortment of several techniques for the measurement of arsenic, and there are important challenges in arsenic detection. Hence, this review opens a scope for those working in this critical area of arsenic determination and its advancement with minimal cost and less risk to health and the environment.
