EFFECT OF pH ON SIMULTANEOUS POTENTIAL ADSORPTION OF Pb, Cd AND Cr IN CONTAMINATED SOIL USING ZEOLITE

Abstract

Porous titanium is one of the leading biomedical materials with high biocompatibility, durability, high stability, and non-toxic to the human body. In this article, we study the effect of pressure on the structure and surface morphology, pore size distribution and porosity and compressive strength of the sample. Sample analyzes used including XRD, EDX, determination of porosity and compressive strength. Samples are sintered at 625 ^oC with pressure from 20 to 50 MPa. The results showed that the porosity of the samples gradually increases when the pressure increases from 20 - 40 MPa. However, as the pressure continues to increase, the porosity of the sample decreases and the compressive strength increases significantly. Samples at 625 ^oC with 40 MPa pressure reached the highest porosity of 61.5%, pore size concentrated in the range of 200 - 350 µm and compressive strength completely suitable for them to be able to apply this material in the field of biomedicine with suitable pore size for the development of bone cells.
