A series of lipophilic weak hydroxy acids, including alkyl phenols and fluorinated alcohols, has been characterized with regard to their ability to extract sodium into 1‐octanol as a function of temperature and extractant concentration. Isotherms are presented at 10, 25, and 60°C, employing ...
what i need to find is the concentration of H+ vs my concentration of HCl. (i am finding percent dissociation. i collected pH data and i found it's equivalence point at 6.58 pH. so i found that it's hydronium concentraton is 2.63 x 10^-7 at it's equivalence point. now i just n...
The molarity is a quantity describing the concentration of a substance in a solution. This can be determined by dividing the number of moles of the solute, n, by the volume of the solution, in liters, V, such that {eq}\displaystyle ...
which enhanced dye adsorption. The maximum adsorption capacity was attained using NaOH-GCB with values of 119.37 mg/g and 91.54 mg/g recorded for EBT and CR, respectively. For both adsorbents, the optimal removal for EBT and CR dyes was obtained at solution pH 2 and 7 due to electrostatic...
the concentration of Cu (II) in the solution was determined, and percentage removal of Cu (II) (%RCu) was calculated using Eq. (1). Control tests were performed at different pH for samples containing heavy metals alone to evaluate the percentage removal of heavy metal by precipitation. The...
Batch studies were performed to evaluate the influence of various experimental parameters like initial pH, contact time, adsorbent dose, initial concentration and temperature on the removal of Brilliant Green. Optimum conditions were found to be initial pH = 2.9, contact time = 3 h and...
First, a lower concentration of NaOH (0.85%) is used for decontamination. Second, the time for decontamination reduces from 15 to 6 min. Third, due to the noninclusion of NALC (which must be prepared and used fresh), PU method is easier to perform. Fourth, time to positivity (TTD), ...
