After completing the pretreatment, the next step is the precipitation reaction. The precipitation reaction is the core step of chemical precipitation for iron removal. By adding an appropriate amount of precipitant, iron impurities form insoluble precipitates in water. Generally, moderately increasing the temperature can accelerate the reaction rate, but excessively high temperatures may lead to poorer crystallinity of the precipitate, affecting the separation efficiency of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC.
Common precipitants include hydroxides and carbonates. Taking hydroxide precipitants as an example, when sodium hydroxide or calcium hydroxide is added to a solution containing iron impurities, the iron ions will react with hydroxide ions to form ferric hydroxide precipitate. Different iron ions can form different precipitates under varying pH conditions, thus affecting the separation efficiency of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC.
The reaction equation is as follows: Fe³⁺ + 3OH⁻ → Fe(OH)₃↓ To achieve the best separation effect of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC precipitate, it is necessary to strictly control the reaction conditions, such as temperature, pH value, and reaction time. Temperature has a significant impact on the rate of precipitation reactions and the properties of the precipitate. The pH value is one of the key factors affecting precipitation reactions.
