      <abstract xml:lang="ru">
        <p>Реагент ОП-4 представляет собой оксиэтилированный алкилфенол со средней степенью оксиэтилирования, равной 4, и применяется при флотации руд. Для количественного определения такого рода поверхно­стно-активных веществ (ПАВ) предложены различные ме­тоды. Однако почти все они применялись для ана­лиза либо чистых ПАВ, либо сравнительно концентрирован­ных растворов. При этом обычно определялись хорошо раст­воримые в воде, в отличие от ОП-4, ПАВ типа ОП-7 и ОП-Ю, имеющие большую степень оксиэтилирования.</p>

        <p>The OP-4 reagent is an oxyethylated alkylphenol with an average degree of oxyethylation equal to 4, and is used in ore flotation. Various methods have been proposed for the quantitative determination of such surfactants. However, almost all of them were used for the analysis of either pure surfactants or relatively concentrated solutions. In this case, surfactants such as OP-7 and OP-Yu, which are highly soluble in water, and have a high degree of oxyethylation, were usually determined, unlike OP-4.</p>
