Kinetic Model Validation With Experimental Data by Linearized 6 Types Equation Derived From Pseudo-Second Kinetic Order Model For Ni (II) İon Adsorption by Siirt Koçpınar Mixed Type Clay

One of the most significant environmental pollutions is water pollution. Water pollution, which is a problem all over the world, has been increasing recently due to unconscious and contemptuous water usage and will inevitably lead to water wars. In this context, it has become a necessity to reduce water pollution and raise awareness among people. One of the effective and inexpensive methods among the studies on this subject is adsorption. The main purpose of this study is to remove Ni (II) ions from aqueous solutions. For this, mixed type clay was used as adsorber. Clay obtained from the Koçpınar town of Siirt is preferred because it can be obtained easily and it’s cost is low. To determine the characterization of the clay, SEM, XRD XRF and FT-IR analyzes were performed. The results obtained from these analyzes showed that the clay was of mixed type. Pseudo-second-order kinetic models are widely applied to data from most adsorption kinetic studies to describe the adsorption mechanism of adsorbate on adsorbent. In this research, 6 different types of pseudo-second order kinetic equations were applied to values at 298 K temperature. The obtained data were applied to six types of linear equations. R2, K2 and qm values were calculated by creating graphs in the light of abovementioned data. As a result of the obtained data, it was understood that adsorption kinetics comply with type 6 equation at most.
