The Use of Sulphophtalein Dyes Immobilized on Anionite AB-17x8 to Determine the Contents of Pb(II), Cu(II), Hg(II) and Zn(II) in Liquid Medium

Abstract

Abstract. 1The conditions of the immobilization of xylenol orange, methylthymol blue, pyrocatechol violet, and chromazurol S at the surface of AB-17×8 anionite were studied. The interaction of Cu(II), Pb(II), Zn(II), Hg(II) ions with obtained solid-phase reagents was investigated. The efficiency of the purification of apple juice with such natural adsorbent of Cherkasy deposits (Ukraine) as palygorskite was studied. The optimum conditions of the reactions, quantitative characteristics of the composition and the surface compound stability, the efficiency of the anion exchanger with the immobilized sulphophthalein dyes were determined.

Airport Runoff Management: Engineering Solutions

“…The treatment of wastewater containing de-icing agents remains unresolved (Revitt et al, 2011), resulting in most of these substances entering the ground and water near airports (Revitt et al, 2011, Xie et al, 2016. For treatment of heavy metal ions that may be contained in effluent, the adsorption treatment stage can often be an important component of a comprehensive treatment technology (Kostenko et al, 2017, Sakalova et al, 2019b.…”

The River System Pollutant Migration in the Context of the Sudden One-Time Discharge with Consideration of the Bottom Sediments Influence (Case of Benzene Migration in the Stryi River, Ukraine)

“…The concentration of benzene at the initial time, for the convenience of further use of the results of mathematical modeling is reduced to 1 g/dm 3 .…”

“…River systems are very important and even critical elements of ecosystems in general and human life in particular. The river systems' ecological safety is largely determined by the efficiency of wastewater treatment technologies [Malovanyy et al, 2016;Shmandiy et al, 2017] and sediment utilization [Tymchuk et al, 2020], adsorption technologies for industrial wastewater treatment [Kostenko et al, 2017;Malovanyy et al, 2019] and other anthropogenic influence formation aspects. Catastrophic spills of oil and petroleum products have very significant consequences for ecosystems.…”

Utilization of drainage water heat in flooded urban areas

“…One of these unconventional energy sources is drainage water discharged from flooded areas. The problem of drainage water treatment is related to its purification from contaminants: ammonium ions (Malyovanyy et al, 2013;Sakalova et al, 2019), phosphates (Tulaydan et al, 2017;Tymchuk et al, 2020;Tymchuk et al, 2021), heavy metals (Kostenko et al, 2017) and their use as non-traditional energy sources.…”
