The Study of Adsorption Efficiency on the Red Blood Cells Membrane Coated

This thesis is concerned with preparing a nanocomposite surface consisting of (red blood cell membranes and polyethyleneimine and characterizing the prepared compound using different techniques. The surface was prepared in several steps. Red blood cell membranes were extracted from human blood through the main blood bank and collected in a Petri dish. The prepared polymers were also added in a ratio of 1:3 to each of the red blood cell membranes and polymers. Polymers are considered solid materials at a temperature of 50 C. Then the compositional, chemical and surface properties of the nanoparticles of the prepared surface were characterized and studied using techniques (FT-IR, XRD and SEM) from its aqueous solutions in several ways. The results indicated that the adsorption process was S-type according to Giles classification and the equilibrium time was 70 min for CV, on CP. Similarly, the analyses showed that the measurements of adsorption for the one dye decreased with increasing temperature at equilibrium, which means that the adsorption was exothermic. Langmuir and Freundlich isotherms were used, and the results showed that the (model Freundlich isotherm) is fit with the experimental data, as it gives correlation coefficients (R2) greater than Langmuir's correlation coefficients.
