摘要

"Method to measure the propensity for fouling and the efficacy of inhibitors of calcium oxalate encrustation, and.Apparatus for measuring the propensity for fouling of calcium oxalate.This invention is directed to a method and apparatus for measuring the rate of formation of fouling of calcium oxalate in a solution of continuous flow having a pH of about 2 to about 3.Comprising measuring the rate of deposition of calcium oxalate encrustation of the solution on a quartz crystal microbalance having a top side and a second side of the funds isolated from soluu00e7u00e3The, in which the pH of the solution is measured using a next of the microbalance measurement module and pH is controlled eletroquimicamente around 3.5 to about 9 and in which the working electrode (23) is coated with or made of a conducting material on which evolution of hydrogen gas continues intensive potential more negative than theS necessary to obtain a pH from 3.5 to 9 near the microbalance (2).
