The effect of some parameters, including pH (1.25-5), phase ratio (O/A: 1/3-2/1), concentration of the extractant (2.5-10% v/v) and extraction duration (5-20 min) were examined. In the investigation of SX, the ranges and experimental parameters chosen are as follows: pH, 3.75; concentration of the extractant, 7.5% v/v; Aqueous /Organic ratio, 3/1 and extraction duration, 10 min. Under these conditions, Cu extraction of 94.62% was achieved. Variance analysis technique (ANOVA) suggested that, the most effective parameter was pH and the less effective parameter was the aqueous /organic ratio. Using of 1.5 M H2SO4 allowed for a stripping efficiency of 98% Cu from the organic phase.eninfo:eu-repo/semantics/closedAccessLix 984NSolvent ExtractionCopperExtraction EfficiencyRobust Design MethodArticle10.1007/s12666-024-03493-82-s2.0-85211926893
