    摘要: The invention relates to a method for analysing a sample comprising at least a first and a second scale inhibitor, which scale inhibitors are synthetic organic compounds comprising at least one ionised group. The method comprises optionally diluting and/or purifying the sample, and allowing the sample interact with a reagent comprising lanthanide(III) ion. The sample is excited at a first excitation wavelength and a sample signal deriving from the lanthanide(III) ion is detected at a signal wavelength by using time-resolved luminescence measurement. The total concentration of the first and the second scale inhibitor is determined by using the detected sample signal, and the concentration of the first scale inhibitor in the sample is determined. The concentration of the second scale inhibitor is determined mathematically by using the obtained results for the total concentration and for the first scale inhibitor concentration.

    摘要: The present embodiments generally relate to the treatment of produced water such as produced water resulting from an industrial process such as one involving the use of copious amounts of water and the addition of one or more polymers such as viscosifying or thickening polymers, in particular enhanced oil recovery processes or another processes resulting in polymer flooded produced water. These treatment methods include contacting the produced water with one or more reducing agents and one or more metals, wherein said treatment may result in a reduction of the viscosity of said produced water and/or the degradation of polymers which are contained therein.
