[0002] In LiPF6 production, wash water specifically refers to the process wastewater generated during the product purification and washing stage. It is an important secondary resource due to its low concentration of recoverable lithium. The core objective of the lithium hexafluorophosphate wash water adsorption lithium extraction unit is to recover valuable lithium resources from the wash wastewater. Among numerous lithium extraction technologies, such as precipitation, extraction, electrodialysis, and membrane methods, adsorption is the preferred method for this scenario due to its high selectivity, simple operation, low energy consumption, and particular suitability for treating low-concentration lithium solutions.
