Abstract
Adsorption is one of the most widely and effective wastewater treatment methods at home and abroad due to its high efficiency, low cost and easy operation. However, the composition of wastewater is complex and the existing background ions will affect the adsorption effect of organic compounds by changing the interaction between adsorbents and adsorbents, causing the problems such as difficult to confirm the main adsorption mechanism and optimize the adsorption conditions. Therefore, it is a significant way to study the effect of ionic strength on the adsorption performance of industrial wastewater. The paper classified the types of adsorbents and expounded the effects of sodium ion and chloride ion on adsorption of organic matter in wastewater under the most common conditions of sodium chloride. Meanwhile, the adsorption mechanism under ion presence condition was preliminarily explained via summarizing the research done by various researchers, and the application and development of adsorbent in wastewater treatment under the ion presence condition were prospected. The development of new, high-efficiency, economical, green and environmentally friendly adsorbents would definitely become the trend of future development.
