D301G is primarily used in water treatment for organic contaminant removal and in hydrometallurgy for the recovery of valuable metals, specifically in gold and copper extraction processes.
The macroporous structure provides a larger surface area and allows for faster ion diffusion, which increases the adsorption capacity and speeds up the separation process compared to gel-type resins.
Yes, Hebei Lijiang Biotechnology produces food-grade D301G resins that are fully compliant with FDA regulations, ensuring safety for sensitive applications.
The recommended regeneration (desorption) protocol involves using 2BV of 3~5% HCl followed by 2BV of 2~4% NaOH.
D301G exhibits excellent chemical stability and mechanical strength, making it resistant to strong acids, alkalis, and oxidizing agents without losing exchange capacity.
Our resins are manufactured under strict quality control and are certified by ISO9001, SGS, and WQA, with specific grades meeting FDA requirements.
