TL;DR: An environment-friendly etching solution not containing ammonia nitrogen comprises, by mass, 0.5-12.0 parts of sodium chlorate, 2.0-20.5 parts of potassium iodide, and 0.8-5.8 parts of corrosion inhibitor.
Abstract: An environment-friendly etching solution not containing ammonia nitrogen comprises, by mass, 0.5-12.0 parts of sodium chlorate, 2.0-20.0 parts of sodium chloride, 1.0-12.0 parts of potassium iodide, and 0.8-5.0 parts of plant extract, 0.1-2.0 parts of complexing agent, 1.5 -8.0 parts of hydrogen peroxide and 0.5-1.8 parts of corrosion inhibitor. The ingredients not containing ammonia nitrogen areadopted to conduct etching treatment on a PCB, the etching treatment of the PCB can be rapidly and accurately completed, and a circuit pattern higher in precision can be obtained; meanwhile, by the adoption of the ingredients better in oxidation property, rapid etching of the PCB can be achieved; especially, plant extracts are added, so that the environmental friendliness of the etching solution is further improved; in addition, by the adoption of the complexing agent and the corrosion inhibitor, it is avoided that the etching solution excessively corrodes the PCB, and the etching accuracy isimproved. In addition, the invention further provides an etching method.

TL;DR: In this article, a method for countering the negative effect of an impurity on an electrode used for the electrosynthesis of sodium chlorate by means of an electrolyte was proposed.
Abstract: The invention relates to a method for countering the negative effect of an impurity on an electrode used for the electrosynthesis of sodium chlorate by means of an electrolyte. According to this method, during electrolysis a substance is added to the electrolyte that reacts with the impurity and prevents it from deteriorating the performance of the electrode. By way of example, the impurity is calcium (Ca 2+ ) and the substance is phosphate (PO 4 3- ).
