Adsorption and removal of precious metals and heavy metals from metal compounds.
The CPs-HP series is a silica powder-type scavenger (adsorbent) that enables metal recovery from metal-containing solutions. It can efficiently adsorb and remove precious metals such as platinum and gold, as well as heavy metals like iron, copper, and nickel, contributing to the reduction of residual metals in pharmaceutical manufacturing, the purification in semiconductor manufacturing processes, and the recycling of precious metals, which are rare resources. It is applicable in columns and can also be used for flow synthesis reactions in continuous production. *For product details and inquiries, please check our company website via the related link.
