ABSTRACT:
The invention concerns an installation for carrying out continuous measurements in real time of masses of metals in an acid solution and measuring the acidity of this solution.
This installation comprises a pipe (1) for circulating this solution, means (2) traversed by the solution to measure the acidity of the latter and providing a signal representative of the value of this acidity, a flowmeter (4) connected to the pipe (1) and traversed by the solution and providing a signal representative of the value of the flowrate of this solution, a spectrometer (7) acting on the circulation cell (6) and providing a signal representative of the intensity of energy peaks respectively corresponding to the values of the concentrations of the metals in the solution, and a computer (9) connected to the means to measure acidity, to the spectrometer and to the flowmeter; this computer is also connected to a memory (9) in which a calculation program is recorded to calculate the respective masses of said metals from the values of the respective concentrations and values of the acidity and flowrate.
