Ultrasonic velocities and densities have been measured for the aqueous solution of manganese sulphate, nickel sulphate and copper sulphate in polyvinyl alcohol solution, in different concentration at 303K. Adiabatic compressibility, intermolecular free length, acoustic impedance, surface tension and other acoustical parameters have been calculated to assess the polymer-ion interaction. It is se...

OBJECTIVES 1) to determine zinc and copper levels of contamination in the individual component solutions used to prepare the pediatric total parenteral nutrition mixtures in Argentina; 2) to compare zinc and copper amounts prescribed by the physician with the true amount given to a neonate weighing 1.2 kg and to a child weighing 10 kg, who would receive total parenteral nutrition formulas prepa...

Groundwater pollution is considered a major concern in today’s world. Most industries Pakistan produce untreated wastewater, extracting from and contaminating nearby water source the soil. This study was conducted Nithar Ke area of Chiniot District to assess impact flow wastewater over on groundwater quality. It aimed to: (1) investigate conditions industrial wastewater; (2) spatial variability...

Due to their physicochemical characteristics, metal oxide nanoparticles (NPs) interact differently with cells compared to larger particles or soluble metals. Oxidative stress and cellular metal uptake were quantified in rat type II alveolar epithelial cells in culture exposed to three different NPs: manganese(II,III) oxide nanoparticles (Mn(3)O(4)-NPs), the soluble manganese sulfate (Mn-salt) a...

In 1947 we (1) described a microcolorimetric method, with a range of sensitivity from 10 to 60 y, for the determination of citric acid in small samples of blood and urine. This method was based on the conversion of citric acid to pentabromoacetone and on the subsequent reaction between pentabromoacetone and alcoholic sodium iodide with the development of a yellow color complex. Hydrazine sulfat...

The development of metal salts-based nanocomposites is highly desired for the Fenton or Fenton-like reaction-based chemodynamic therapy cancer. Manganese sulfate (MnSO4)-dispersed nanoparticles (NPs) were fabricated with a hot-melt extrusion (HME) system colorectal cancer in this study. MnSO4 was homogeneously distributed polyethylene glycol (PEG) 6000 (as hydrophilic polymer) aid surfactants (...

Abstract This study re-assess the environmental impacts of Dexing copper mine (the largest open-pit in Asia) on Lean river and its two tributaries Dawu Jishui river) Jiangxi province, China, with particular focus metal pollution as well effectiveness side-effects remediation activities. Results show that mixing zone were still heavily influenced by acid drainage (AMD) loaded elevated levels met...
