Packaging Details Organic acid production In the process of organic acid fermentation, lye must be added to control the pH value of the fermentation liquid, so the sodium salt solution of organic acid is formed after fermentation. The conversion of organic acid sodium salt to organic acid is a basic step in the production process. Traditional Method 1: Cation exchange resin (produces a lot of wastewater) Traditional Method 2: Lime precipitation, sulfuric acid dissolution (producing a lot of wastewater and waste residue) Bipolar membrane method: the organic acid sodium salt is directly converted into organic acid and sodium hydroxide, the production process does not need to add acid, there is no pollutant discharge, the formed lye can be reused in production, and has obvious economic and social benefits. Organic acids: citric acid, lactic acid, tartaric acid, gluconic acid, succinic acid, etc

Product Description

Bipolar membrane is a kind of thin film material with many applications. Its special structure and properties make it widely used in battery, separation, catalysis and other fields.

In the field of batteries, bipolar membranes can be used to prepare various types of batteries, such as lithium-ion batteries, sodium-ion batteries, lead-acid batteries, etc. Its application can improve the energy density of the battery, reduce the internal resistance, extend the life and so on. For example, in lithium-ion batteries, the double can isolate the charge between the anode and cathode, prevent the battery from short circuit, and also avoid the mutual reaction between the anode and cathode, improving the cycle life of the battery.

In the field of separation, bipolar membranes can be used for ion exchange, membrane filtration, etc. For example, in desalination seawater can be desalted by isolating salt and water molecules through selective channels of positive and negative ions. In the chemical industry, it can also be used in the process of acid-base separation and purification of organic matter, with high separation efficiency and selectivity.

In the field of catalysis, bipolar membranes can be used to prepare catalysts and accelerate chemical reactions. For example, in electrochemical synthesis reactions, it can be used as a catalyst carrier to improve reaction rate and selectivity. In organic synthesis, it can also be used in photocatalytic reactions and electrocatalytic reactions to perform functional modifications on various organic molecules.
