By Ratna S. Shelke, Jagdish V. Bharad, Balaji R. Madje and Milind B. Ubale

Abstract

The study was performed to investigate the use of Jaswand plant material (Hibiscus rosa-Sinensis) as an adsorbent for the removal of Ni (II), Cu (II) and Fe (III) from aqueous solution.  FT-IR characterization of Jaswand Leaf Powder (JLP) done by standard procedures. The adsorption process was carried by batch experiments by varying adsorbent dose, pH of the adsorbate (metal ion) solution, temperature and time. The percentage removal of Ni (II), Cu (II) and Fe (III) by JLP under different condition during the findings was significant and is enlisted in the tabular form as:

 

Condition

Percentage removal of metal ions

Minimum

Maximum

pH
Adsorbent dose
Initial Conc. of Adsorbate
Temperature

23.80
37.00
43.00
55.60

74.50
63.70
53.08
70.50

The order of adsorption during the findings on JLP of metal ions were Ni > Cu >Fe. The equilibrium adsorption data were fitted with Freundlich, Langmuir Isotherms. A time variation study indicates that adsorption follows pseudo-first order kinetics.
