        <p>Gossipol asosida olingan Shiff asoslari ayrim metallar bilan maxsus sharoitlarda o‘ziga xos rangli birikmalar hosil qiladi. Gossipol birikmalarining ushbu xossalariga asoslanib ularni analitik kimyoda metall ionlarini aniqlashda reagent sifatida ishlatilishi mumkin. Ushbu maqolada Co3+ kationini miqdoriy va sifat tahlilini o‘tkazishda 2-amino 4-metil piridindan foydalanish imkoniyatlari, ushbu kompleksni olish sharoitlari va xossalari o‘rganildi. Gossipol 2-amino 4-metil piridinning kobalt (III) ioni bilan kompleks hosil qilishining optimal sharoitlari ya‘ni eritmaning pH muhiti, reagent miqdori, bufer tarkibiga bog‘liqligi, vaqtga nisbatan barqarorligi va quyilish tartibi o‘rganildi.  Hosil bo‘lgan komplekslar nur yutishga asoslangan spektrofotometr, IQ spektroskopiyasi, skanerlovchi elektron mikroskopiya usullari yordamida o‘rganildi, shuningdek komplekslarning tarkibi Izomolyar serialar metodida tahlil qilindi va kompleks uchun Me:R o‘zaro 1:3 nisbatta ekanligi aniqlandi. Kompleks hosil bo‘lishidan olingan natijalar tahlil qilindi va matematik qayta ishlandi. Olingan natijalarga ko‘ra hosil bo‘lgan komplekslar o‘rtacha barqarorlikka ega ekanligi aniqlandi.</p>

        <p>Schiff bases obtained on the basis of gossypol form distinctive coloured compounds with certain metals under special conditions. On the basis of these properties of gossypol compounds, they can be used as reagents for the determination of metal ions in analytical chemistry. This article studies the possibilities of using 2-amino 4-methylpyridine in carrying out the quantitative and qualitative analysis of the Co3+ cation, as well as the conditions for obtaining this complex and its properties. The optimal conditions for the formation of a complex of gossypol 2-amino 4-methylpyridine with the cobalt (III) ion were studied, namely the pH of the solution, the amount of reagent, the dependence on the buffer composition, the stability over time and the order of addition. The resulting complexes were studied by means of absorption-based spectrophotometry, IR spectroscopy and scanning electron microscopy; the composition of the complexes was also analysed by the method of isomolar series, and the Me:R ratio for the complex was found to be 1:3. The results obtained from the formation of the complex were analysed and processed mathematically. According to the results obtained, it was established that the complexes formed possess moderate stability.</p>

        <p>Основания Шиффа, полученные на основе госсипола, в особых условиях образуют с некоторыми металлами уникальные окрашенные соединения. Благодаря этим свойствам соединений госсипола можно использовать в качестве реагентов для определения ионов металлов в аналитической химии. В данной статье изучены возможности использования 2-амино-4-метилпиридина в количественном и качественном анализе катиона Со 3+ , условия получения и свойства этого комплекса. Изучены оптимальные условия образования комплекса госсипола 2-амино-4-метилпиридина с ионом кобальта (III) - рН раствора, количество реагента, зависимость от состава буфера, стабильность во времени и процедуры разлива. Образовавшиеся комплексы изучали с помощью абсорбционного спектрофотометра, ИК-спектроскопии, сканирующей электронной микроскопии, анализировали состав комплексов методом изомолярной серии и установили, что соотношение Me:R для комплекса составляет 1:3. Результаты, полученные при формировании комплекса, были проанализированы и математически обработаны. По полученным результатам установлено, что образовавшиеся комплексы обладают умеренной устойчивостью.</p>
