The three secondary hydroxyl groups on 2 are nicely arranged for H-bond donation to a single anion, and may be converted into stronger neutral or positively-charged H-bond donors.
Hence the impact of increasing single anion concentrations between 10 and 250 mg/L for chloride, nitrate, carbonate, and sulfate on the recovery of 1.5 µg/L perchlorate solutions was investigated.
Single anion and mixed anion solutions of different concentrations were used for the experiments.
Single anion release medium of carbonate was found to yield the highest release percentage of 2,4-D at 99%.
In this study, we have 135 cations bonded to a single anion (O2−), and thus.
A n − can be single anions (such as Cl− or OH−), trigonal planar anions (CO, NO ), tetrahedral anions (SO, CrO ), octahedral anions ([Fe CN 6]4−) or alumino-silicate sheets (Drits & Bookin, 2001 ▶).
Borrok et al. [ 72] presented a new method for efficient separation of Cu, Fe, and Zn from the greater concentrations of matrix elements using a single anion-exchange column with hydrochloric acid media.
Single-anion conducting polyether networks have been synthesized and investigated.
In contrast, anions with higher hydration abilities adsorbed less readily in the mixtures than in the single-anion solution.
