Freshwater contamination remains a challenging issue for the sustainable management of wetland ecosystems. This study aims to evaluate water quality Jhilmila Lake, Kanchanpur, Nepal by adopting standard test procedures, geochemical indices, and multivariate statistical analysis. The surface samples were collected during postmonsoon season in 2018 assess hydrochemical parameters such as pH, elec...

We conducted reversed deliquescence experiments in saturated NaCl–NaNO3 – H2O, KNO3 – NaNO3 – H2O, and NaCl–KNO3 – H2O systems from 90 to 120 °C as a function of relative humidity and solution composition. NaCl, NaNO3 , and KNO3 represent members of dust salt assemblages that are likely to deliquesce and form concentrated brines on high-level radioactive waste package surfaces in a repository e...

-Ion-exchange isotherms between hydrotalcite-like compounds (HT) of the NO3-, CI-, and SO4forms and F , 0% Br , I , OH-, SO42-, CO3 z-, and Naphthol Yellow S (NYS 2-) ions were determined, and the spacing and the width of the 003 reflection were measured as a function of HT composition. The ion-exchange equilibrium constant for HTs of monovalent anions are in the sequence OH> F > Cl > Br> NO3> ...

Similar reactions of 2,6-dipicolinoylbis(N,N-diethylthiourea) (H2L(a)) with: (i) Ni(NO3)2·6H2O, (ii) a mixture of Ni(NO3)2·6H2O and AgNO3, (iii) a mixture of Ni(OAc)2·4H2O and PrCl3·7H2O and (iv) a mixture of Ni(OAc)2·4H2O and BaCl2·2H2O give the binuclear complex [Ni2(L(a))2(MeOH)(H2O)], the polymeric compound [NiAg2(L(a))2]∞, and the heterobimetallic complexes [Ni2Pr(L(a))2(OAc)3] and [Ni2Ba(...

Assessing water quality is necessary to ascertain its viability for domestic, industrial, and agricultural purposes. A total of 48 samples were, respectively, drawn from the Rivers Karawa Iyiaji located in Ezeagu Uzo-uwani which are typical rural areas Enugu State, Nigeria. These were taken two seasons (early rainy season late dry season). Physicochemical properties determined using standard me...

Zero-valent iron/peroxymonosulfate (Fe0/PMS) has been considered as a promising approach for wastewater treatment. Anions and cations are widely present in have significant effects on the performance of Fe0/PMS system Thus, study, tartrazine was selected target model; SO42−, NO3−, HCO3−, Cl− were representative anions Ca2+, Cu2+, Mg2+, Mn2+ chosen cations. The effect these removal major radical...
