Large amounts of chloride ions (Cl−) and sulfate ions (SO42−) are present in salt-washing wastewater, making it unsuitable for direct release. Adsorption can be used to eliminate Cl− and SO42− from salt-washing wastewater, and hydrotalcite is an excellent adsorbent with high adsorption properties for these ions because of a layered bimetallic …
