Study of solid phase adsorption of paralytic shellfish poisoning toxins (PSP) onto different resins

► Solid phase adsorption system onto different polymers/resins (CDP and SP700). ► Both materials adsorb a wide range of PSP toxins from dinoflagellates cultures. ► Toxins adsorption from 3 to 7 days and recovery of toxins in water and methanol. ► CDP appears more appropriate since it adsorbs higher quantities of PSP toxins. ► SP700 adsorbing DSP and also PSP toxins seems to be more useful.
