    The technology of obtaining complex anticorrosive pigments from zinc-containing waste water
    (Publishing House of Lviv Polytechnic National University, 2013) Frolova, Liliya; Shuvalov, Valentin
    The technique for environmental protection from heavy metals is proposed in this paper. The objective of this research is development of utilization technology of metal-containing hazardous sewage with the reception of anticorrosive pigments. Zinc containing model solutions and waste water were used for this study. Cobalt was used as a cation chromophore. The method of potentiometric titration has been applied for research of precipitation process. X-ray phase analysis, electron microscopy, derivatograph method, power dispersion spectrometry, and spectrophotometric methods were used to learn the pigment properties. Запропоновано метод захисту довкілля від важких металів. Об'єктом дослідження є технологія очищення стічних вод з одержанням антикорозійних пігментів. Як хромофор використано катіон кобальту. Методoм потенціометричного титрування досліджено процес осадження. Властивості одержаного пігменту вивчено за допомогою рентгенофазового аналізу, електронної мікроскопії, енергодисперсійної спектрометрії, спектрофотометрії.
