Modified Zeolite and Treatment with Cr³⁺ in the Wastewater

Abstract:

The ultra-zeolite is an important research topic at present. Using ultra-zeolite 4A to treat wastewater has the advantage that traditional methods do not have, so it has been concerned by many experts and scholars. This subject adopts microwave method to synthesize ultra-zeolite 4A. Then using the prepared ultra-zeolite 4A to adsorb Cr³⁺in wastewater. Study on the effect factors such as pH value, adsorption temperature, etc. The conclusion shows that ultra-molecular sieve 4A has been successfully synthsized by microwave method. In experiment of absorption wastewater containing Cr^{3 +}we has found when the concentration of solution containing Cr^{3 +}is 400mg / L, pH =4, temperature is 25 and adsorption time is10 minutes, which ultra-zeolite 4A removes Cr³⁺ is better.
