Study and Application on Separation and Enrichment of Cobalt-Ozyteracycline Complez by Aqueous Two-phase Gas Floatation
A novel and green method for separating and enriching trace OTC in environment water by Aqueous Two-Water phas Gas Floatation Spectrophotometry has been proposed, the principium was discussed. The method estimated by HPLC was good. In this paper, the hydrophobic complex composed of Co(II) and OTC was floated into organic phase under the optimal conditions: pH=9, the floatation equipment is home-made, tetrahytrofuran as organic solvent ,sodium chloride as separating phase reagent. The data were obtained by spectrophotometry after floatation; The linear regression equation is A=1.447×105 C+0.0321, linear ranges is from 1×10-7 to 9.1×10-5 mol·L-1, respectively, with the correlation coefficient (r) better than 0.9995, The relative recoveries is 100.1–102.3% , limit of detection is 3.8 ×10-8 mol·L-1 , It can be applied to analyse the trace OTC in water sample, the result is better.
