The prototype of instrument was planned and under the developing for separation of arsenic from drinking water. The highly iron doped calcium alginate is the chemical agent to keep the arsenic species (anions in III and V oxidation stage) on the gel column. The objective is to enrich the capability of production at a concentration of 10 g L -1 arsenic in 1 m 3 of purified water with cost less than 4 USD. During the developing 77 As and 75 Se radioisotopes traced the separation. The PLC automated system unit can communicate even trough satellite, and the alginate waste satisfies the "green chemistry" terminology. Megjegyzés [T1]:The reference must be cited by the first author
