摘要

system for total removal and recovery of ammonium contained in complex matrices, their use, and process for removal and recovery of ammonium contained in complex matrices. the present invention relates to a system for total removal and recovery of ammonium contained in complex matrices such as, for example, wastewater, thermal springs, or broths for cultivation of antibiotic-producing microorganisms, which comprises a container (1); a sealing stopper (2); an injection device (3); a hose (m1) for inert gas inlet; a hose (m2) for exhausting gases; a condenser (4); a collecting container (5) for collecting the gases; and a sprinkler (6). using the system of the present invention, the ammonia gas and water vapor from the container (1) and the inert gas introduced in this container are drawn through the hose (m2) through the condenser (4) with cold water circulation at 15 ° c, then, received in a collecting container (5) containing 0.1 mol / l hcl solution where the ammonia gas is converted into ammonium ions. these ions are then quantified with an ion selective electrode (lo), without interference from other ions present in that matrix.
