Abstract The release of effluents from automobile industries contains various metal
ions which has to be removed effectively. This can be done eco-friendly using
biosorption. Ni (II) ions were adsorbed using seeds of Mirabilis jalapa. The seeds
showed maximum adsorption activity without activation. Optimization studies were
carried out to achieve maximum removal efficiency. The parameters included in
the study were pH, contact time, metal ion concentration, RPM, adsorbent dosage
concentration and temperature. The equilibrium data showed that the adsorption fits
Harkins–Jura isotherm model. Kinetics studies revealed that the adsorption follows
pseudo-first-order kinetics. Further, optimization studies were carried out using BoxBehnken design, and the obtained data reveals that the model is significant. Modification in the functional groups were studied using FTIR analysis, and the results
were interpreted.

1 Introduction
The presence of a huge number of industries around water sources has led to water
pollution on a large scale. Only 1% of the total water on our planet is suitable for
drinking and yet industries pump in tonnes of toxic heavy metal waste every day,
which makes it extremely hazardous. Nickel, the metal chosen for study, constitutes
a major portion of the effluent released from finishing industries such as electro
galvanic industries. Tap water faucets, nickel-steel alloy cookware and coins are some
main sources of nickel toxicity in water (Cempel and Nikel 2006; Aikpokpodion et al.
2010). Electroplating industries use nickel in large quantities and recycling it can
