Abstract in another language

Co-elution of cationic methylated arsenic, e.g. arsenobetaine may interfere with the determinationof arsenite on the Hamilton PRP-X100 anion-exchange column using a phosphatebuffer isocratically. Therefore, a sample pre-treatment method with self-packed AG MP-50 cation-exchange cartridges was proposed, which enables the arsenite determination insamples containing arsenobetaine on a PRP-X100 column using a phosphate buffer (pH5.6) isocratically. Methylated arsenic, including dimethylarsinic acid, trimethylarsine oxide,tetramethylarsonium ion, arsenobetaine and arsenocholine, with concentrations below1000gAsL−1, may be completely retained in the AG MP-50 cartridge without any changesof arsenite, arsenate and monomethylarsonic acid speciation. Such retention was independentof the pH and matrix. It is proposed to be based on hydrophobic interaction. With thehelp of AG MP-50 cartridges, 11 arsenic species were detected in fish (DORM-2), mussels(BCR-477) and red algae (Porphyra tenera) in 10 min on the PRP-X100 column using a phosphatebuffer isocratically. Arsenite was the only minor species (up to 0.9%) among all waterextractable arsenic species in fish, mussel and red algae
