Decolorization and MIneralization of Methylene Blue in Aqueous Solutions by Persulfate/Fe2+ ProcessJournal of Water Chemistry and Technology - Tập 42 - Trang 244-251 - 2020
Mostafa Mahdavianpour, Saeid Ildari, Mehdi Ebrahimi, Mehrdad Moslemzadeh
Today, the treatment of dye wastewater discharged by various industries, such as
textiles, has attracted the attention of many researchers due to the
non-biodegradability nature of dye contaminants. Methylene blue is one of
numerous dyes existing in this wastewater that causes a variety of human health
problems. Because of the low efficiency of biological treatment processes in the
removal of this... hiện toàn bộ
Biochemical treatment of petroleum-containing watersJournal of Water Chemistry and Technology - Tập 35 - Trang 183-188 - 2013
E. I. Semenova, N. A. Bublienko, T. A. Shilofost, A. V. Bublienko
The article has investigated the processes of treating petroleum-containing
wastewaters by means of an aerotank mixer and their intensification was carried
out by the unit of biochemical purification, which is a foam tank and aerotank
clarifier.
Photometric Extraction Detection of 2-Methyl-4-Chlorophenoxyacetic Acid in WaterJournal of Water Chemistry and Technology - Tập 44 Số 5 - Trang 362-368 - 2022
Zholt Kormosh, Shevchuk, Mykola, Kormosh, Natalia, Korolchuk, Svitlana, Savchuk, Tetiana, Suprunovich, Sergei
It has been shown that 2-methyl-4-chlorophenoxyacetic acid (MCPA) forms an ionic
associate (IA) with the polymethine dye Astrafloxin FF (AF). The energy
efficiency of IA formation is substantiated by the method of mathematical
modeling. The molecular modeling of MCPA– + AF+ systems and related calculations
are performed by using the HyperChem 8.0 software package in various initial
variants for th... hiện toàn bộ
Water purification of sulfates by liming when adding reagents containing aluminumJournal of Water Chemistry and Technology - Tập 36 - Trang 70-74 - 2014
N. D. Gomelya, I. N. Trus, Yu. V. Nosacheva
The article has investigated the processes of water purification of sulfates
when treating with lime, sodium aluminate or aluminum hydroxide. It has been
shown that the efficiency of removing sulfates depends on the type and
consumption of reagents containing aluminum and the method of pretreating
aluminum hydroxide. The paper has determined the effect of after treatment by
carbon dioxide or magne... hiện toàn bộ
Removal of Fluoride from Aqueous Solution using Calcium Peroxide as a Low-cost AdsorbentJournal of Water Chemistry and Technology - Tập 42 - Trang 329-338 - 2020
Parwathi Pillai, Swapnil Dharaskar, Hitesh Panchal
Removal of fluorides from water is essential for humans and animals because it
causes dental and bone deficiency. The maximum permissible limit of fluoride is
1.5 mg/L, according to the World Health Organization. Recently it became known
that countries like Pakistan, India, Sri Lanka, China, Argentina, etc. have high
fluoride concentration in groundwater. In the present work, calcium peroxide
nano... hiện toàn bộ
Phylogenetic diversity of aqueous microorganisms separated after the advanced tertiary of tap waterJournal of Water Chemistry and Technology - Tập 36 - Trang 184-189 - 2014
I. Yu. Roi, N. A. Klimenko, G. M. Zdorovenko, V. V. Goncharuk
The species composition of bacterial community of the drinking tap water and
water samples taken at different purification stages of the water conditioning
plant at an enterprise producing special drinks has been analyzed. This study
involves the analysis of 16S rRNA gene sequences and the use of molecular
biology methods based on the phylogenetic analysis. The following bacterial
species were ide... hiện toàn bộ
The impact of activated carbon oxidizing on the adsorption of fulvic acids from aqueous solutions under dynamic conditionsJournal of Water Chemistry and Technology - Tập 33 - Trang 230-235 - 2011
T. V. Polyakova, N. A. Klimenko, L. A. Savchina, E. A. Samsoni-Todorova
The paper has investigated the adsorption of peat fulvic acids from aqueous
neutral solutions on unoxidized and oxidized activated carbons under dynamic
conditions. We have determined the share of biologically accessible organic
carbon in the value of total organic carbon in the course of biofiltration. It
has been shown that the generation of biologically accessible organic carbon on
oxidized car... hiện toàn bộ
