Abstract
A quick and sensitive determination method was developed for arsenic species traces in surface and drinking
water via stripping voltammetry techniques. A hanging mercury drop electrode (HMDE) was used as working
electrode. As (III) is determined directly and As (V) is calculated by subtraction between total As and As (III).
In order to determine total As, the entire quantity of arsenic is reduced to As (III), which represents the
electrochemical active specie. A large number of tests were performed in order to achieve the optimum
setup of equipment’s parameters, studies on a large range of interference's were done and at the end the
method was in house validated.
