NETIS registration (HK-100015-A)! Strongly adsorbs heavy metals.
The heavy metal countermeasure material "Adrock" includes heavy metal adsorbents used in the adsorption layer method, "Adrock Sand P" and "Adrock Steel D/S," as well as heavy metal immobilization materials used in the immobilization method, "Adrock Magnum" and "Adrock Natural G/S." The adsorption layer method is a countermeasure that prevents heavy metals from permeating underground by laying an adsorption layer on embankments of rocks and soils containing heavy metals. 【Features】 [Common Features of Heavy Metal Adsorbents] ○ Capable of adsorbing various heavy metals ○ Strongly adsorbs heavy metals, preventing re-dissolution even during environmental changes ○ Powder form allows for easy mixing with soil [Features of Heavy Metal Immobilization Materials] ○ Capable of adsorbing various heavy metals ○ Wide environmental adaptability For more details, please contact us or download the catalog.

basic information
【Product Lineup】 [Heavy Metal Adsorbents] ○ Adrock Sand P (Layered Double Hydroxide Material) → Capable of adsorbing various heavy metals → Can be accurately mixed using a self-propelled soil improvement machine ○ Adrock Steel D (Iron Compound Material) → Excellent adsorption capacity for selenium due to high reduction ability ○ Adrock Steel S (Low Crystallinity Iron Composite Material) → Adsorbs safely and easily in neutral pH range [Heavy Metal Immobilization Materials] ○ Adrock Natural G → Gypsum-based material that improves soil quality without significantly changing soil pH → Also has immobilization effects on heavy metals such as arsenic ○ Adrock Natural S → Material primarily composed of low crystallinity iron oxide and calcium sulfate → Exhibits high immobilization effects due to its characteristics of ultra-fine particles and low crystallinity ○ Adrock Magnum → Low alkalinity magnesium-based material → Highly effective in preventing leaching of amphoteric metals such as lead due to its pH of around 10 ● For more details, please contact us or download the catalog.
