A novel analytical procedure for the determination of gold by electrothermal atomic absorption spectrometry combined with selective liquid-liquid extraction by natural deep eutectic solvents(NADESs)is *** extraction ability of the NADESs prepared using menthol,thymol and camphor toward gold in hydrochloric acid solutions was *** extraction efficiency was improved by optimizing the parameters including the composition of the NADES s,the volume ratio of organic and aqueous phases,kinetics,and acidity of the *** determination of gold was carried out by electrothermal atomic absorption spectrometry directly in the NADES s phase dissolved in isopropyl *** extraction recovery of gold from 1 mol/L HCl with the NADESs based on menthol and camphor mixed in a molar ratio 1:1 was 99.7%at an enrichment factor of *** limits of detection and quantification of the proposed procedure were 1μg/L and 3.3μg/L,respectively,with a relative standard deviation of less than 5%.The developed procedure was applied for determination of gold in the certified reference material of ore,environmental and waste waters.

AIM:To assess and compare the efficacy and safety of two triple regimes:A)metronidazole,amoxicillin and omeprazole, which is still widely used in Russia,and B)azithromycin, amoxicillin and omeprazole in healing active duodenal ulcer and *** eradication. METHODS:100 patients with active duodenal ulcer were included in the open,multicentre,randomized study with comparative *** were randomly assigned to one of the following one-week triple regimes:A) metronidazole 500 mg bid,amoxicillin I g bid and omeprazole 20 mg bid(OAM,n=50)and B)azithromycin 1 god for the first 3 days(total dose 3 g),amoxicillin 1 g bid and omeprazole 20 mg bid(OAA,n=50).Omeprazole 20 mg od was given after the eradication course as a monotherapy for three *** control endoscopy was performed 8 weeks after the *** was determined in the entry of the study and four weeks after the cessation of treatment by means of histology and CLO-test. RESULTS:97 patients completed the study according to the protocol(1 patient of the OAM group did not come to the control endoscopy,2 patients of the OAA group stopped the treatment because of mild allergic urticaria).Duodenal ulcers were healed in 48 patients of the OAM group(96 %, C190.5-100 %)and in 46 patients of the OAA group(92 %, CI 89.5-94.5 %)(p=ns).*** was eradicated in 15 out of 50 patients with OAM(30 %,CI 17-43 %)and in 36 out of 50 patients treated with OAA(72 %;CI 59-85 %) (P<0.001)-ITT ***: The triple therapy with omeprazole, amoxicillin and metronidazole failed to eradicate ***'vc\ the majority of patients, which is an essential argument to withdraw this regimen out of the national recommendations. Macrolide with amoxicillin are preferable to achieve higher eradication rates. Azithromycin (1 g od for the first 3 days) can be considered as a successful component of the triple PPI-based regimen.
