Does Poly-Filter® remove "Trace Elements" from
freshwater or marinewater?
NO!! In synthetic seawater the American Society of Testing & Materials states "Barium, Manganese, Copper, Zinc, Lead, Silver are the only added trace elements occurring in substitute ocean water" Standard D 1141. ASTM further states "Trace element occurring naturally in concentrations below 0.005 mg/L are not included". In other words naturally occurring impurities are not considered. The sodium chloride adds iron at 0.255 - 0.398 mg/L concentration to synthetic seawater mixes. Ref. Morton Salt's Purex Analysis. Many of the other listed trace elements concentrations are below the part-per-billion detection range via Atomic Absorption w/Graphite Furnace. Simply, those other 40_ trace elements presence can't be detected or proven under modern EPA Methods of Analysis.
