Evaluation of adsorption capacity by porcelain made of palygorskite and cow bone to heavy metals ions (Cu+2, M n+2, and Pb+2)‎

الملخص EN

In this study kinematic energy of porcelain made of Palygorskite clay and cow bone.

Solutions containing ions of Pb+2, M n+2, and Cu+2, were prepared at different concentrations (10, 20, 40, 60, and 80)mg / l, to measure the adsorption capacity of the porcelain to these ions.

The adsorption capacity were computed according to several kinematic models.

The most important models were Langmuir model and Freundlich models.

The results showed variety in adsorption capacities for each heavy metal.

Results of adsorption capacities according to Freundlich model were: Cu>Mn>Pb.

Where maximum capacity was for Cu(3.751mg/g), and minimum was for Pb (2.419mg / g).

While the results according to Langmuir model were: Pb> Cu> Mn, and the capacities were nearly equal for the three ions.

They were for Pb (0.891 mg/g), for Cu(0.8165mg/g) and for Mn (0.801mg / g).
