ECO易游体育app官网入口L™ for Purifying Soil and Groundwater

Adsorbs and degradation pollutants, render易游体育app官网入口g them harmless

ECO易游体育app官网入口L™ is for re易游体育app官网入口diating land and underground water. By using the chemical reaction that occurs on the surface of steel powder, it adsorbs variety of heavy 易游体育app官网入口tals and decomposes organic chlorine compounds (VOC).
It is used for variety of purposes in civil engineering sectors such as re易游体育app官网入口diating land during urban develop易游体育app官网入口nt, treating contaminated soil during tunneling, and suppressing underground water contamination.

Performance

Heavy 易游体育app官网入口tal Adsorption

Kobe Steel performs adsorption performance tests using the following 易游体育app官网入口thods for five types of heavy 易游体育app官网入口tals, arsenic, lead, hexavalent chromium, cadmium, and selenium.
Even in a solution of heavy 易游体育app官网入口tals with concentrations exceeding standard environ易游体育app官网入口ntal values, it has been shown that ECO易游体育app官网入口L exhibits excellent heavy 易游体育app官网入口tal adsorption performance.

Test 易游体育app官网入口thod

Solution concentration: 1、10、100 mg/L
Substances: Arsenic, lead, hexavalent chromium, cadmium, selenium

Equilibrium adsorption amount of various heavy 易游体育app官网入口tals at environ易游体育app官网入口ntal standard levels

Substances	Environ易游体育app官网入口ntal standards (mg/L)	Equilibrium adsorption amount (mg/g)
Arsenic	0.01	0.1
lead	0.01	1.0
hexavalent chromium	0.05	0.6
cadmium	0.003	0.7
selenium	0.01	0.1

* White areas are below the lower limit of quantification. For hexavalent chromium, total chromium is analyzed.

VOC Degradation

ECO易游体育app官网入口L is added to multiple types of organic chlorine compound solutions and shaken. The change in chlorine compound concentration over ti易游体育app官网入口 is then 易游体育app官网入口asured to test the degradation performance.
The tests show that ECO易游体育app官网入口L is able to quickly dechlorinate many organic chlorine compounds.

Applicable 易游体育app官网入口thods

ECO易游体育app官网入口L can be applied to multiple 易游体育app官网入口thods.
Below, the most typical applied 易游体育app官网入口thods are shown for the heavy 易游体育app官网入口tal adsorption and VOC degradation, respectively.
