Nitric acid and other strong oxidizing agents can cause explosive reactions when mixed with ion exchange resins. Proper design of process equipment to prevent rapid buildup of pressure is necessary if use that.
Ion exchange resins and adsorbents as produced, contain by-products resulting from the manufacturing process. The user must determine the extent to which organic by-products must be removed for any particular use ad establish techniques to assure that the appropriate level of purity is achieved for that use. The user must ensure compliance with all prudent safety standard and regulatory requirements governing the application.
