ACD-18 is a chelating resin with high selectivity, featuring a cross-linked polystyrene framework. Its functional groups are meticulously engineered to effectively and selectively chelate and adsorb nickel ions (Ni²⁺) in intricate solution systems, particularly in settings abundant with iron (Fe²⁺/Fe³⁺), copper (Cu²⁺), zinc (Zn²⁺), and various other prevalent metal ions. This resin has addressed a critical technical challenge of separating nickel from iron in areas such as hydrometallurgy, electroplating wastewater management, and battery recycling, enabling the high-purity recovery and concentration of nickel elements.
Product features
Exceptional Selectivity: This product exhibits an extremely strong affinity and selectivity for nickel ions (Ni²⁺). Within the optimal pH range of 3 to 6, it can efficiently overcome competitive interference from iron ions (Fe³⁺), enabling effective separation of nickel and iron.
High Adsorption Capacity: Featuring a relatively dense arrangement of functional groups, the resin boasts a theoretical saturated adsorption capacity for nickel of at least 0.8 mmol/g (wet resin), or even higher.
Superior Physical and Chemical Stability: The rigid styrene-divinylbenzene framework provides the resin with excellent mechanical strength, wear resistance, and resistance to acids and alkalis, making it ideal for long-term, cyclic use.
Outstanding Kinetic Performance: The resin particles possess a reasonable pore size distribution, facilitating rapid mass transfer and ensuring high adsorption and desorption efficiency.
Excellent Regeneration Performance: Adsorbed nickel ions can be readily eluted using common inorganic acids, such as sulfuric and hydrochloric acid, for resin regeneration. This results in a long cycle service life.
