Study on Concentration and Reservation of Trace Petroleum from Waste Water Using GDX Resins

LI Guanbin LI Zhijun (Shandong Institute of Light Industry, Jinan 250100) GAO Liancun WANG Shuren (Shandong University, Jinan 250100)  
Two micromolecular porous resins, GDX-102 and GDX-502, were used to concentrate the trace petroleum in water. The conditions of concentration, elution and reservation have been studied. It has been shown that both GDX resins are of high concentration efficiency and large adsorptive capacity. Ethylether was the best eluting agent among 9 agents with the elution efficiency of 101.2% for GDX-102 and 99.4% for GDX-502. The experimental results showed that the best reservation method was in dry state of nitrogen. After seven days the loss of petroleum on GDX-502 was less than 4.6%.
