10.22376/ijpbs.2019.10.1.p1-12 Volume 4 Issue 1 2013 (January - March) To study the extent of removal of Cu(II) ions from the electroplating industrial effluent, metal resistant fungal strain of lessThan i greaterThan Penicillium janthinellum lessThan /i greaterThan was selected for the present study. Response surface methodology was used to optimize the sorption process variables i.e. temperature (20-40 ºC), biomass concentration (0.5-2.5 mg/l), pH (2.0-6.0) and initial concentration of metal ions (20-100 mg/l). The maximum removal 59.48% of Cu (II) ions was observed at temperature 33.7 °C, biomass concentration 1.65 g/L, pH 5.88, and metal ions concentration 60.12 mg/L. Experimental results shows that sorption of Cu (II) ions by lessThan i greaterThan P. janthinellum lessThan /i greaterThan indicates good biosorbent for removal of heavy metals from aqueous solution. However, the Cu(II) ions removal efficiency by lessThan i greaterThan P. janthinellum lessThan /i greaterThan in electroplating industrial effluent was found to be 35â„….
