“…The subscript 'x' refers to the aggregation number of NaD. Dinonyl naphthalene sulfonic acid is known to form micelles exhibiting a critical concentration of ~ 10" 6 F and an aggregation number that is considered relatively constant dependent upon the specific system and approximately equal to 10 [11,12].…”

Np(V) sulfate /Aqueous complex /Stability constants AbstractThe stability constant of the monosulfate complex of Np(V) has been measured at ionic strengths of /= 0.5, 1.0 and 2.0 and at temperatures of 5, 25 and 45 °C. Entropy and enthalpy values for the process of complex formation have been shown to have relatively large positive values. Inner sphere complexing appears to be supported by these measurements.

“…The aggregation number (n) of HDDNS in CCI4 was determined from extraction data using a method of slope analysis (13)(14)(15)(16) Condition iv requires both using constant aqueous ionic strength and limiting the concentration of HDDNS.…”

“…the Zn(ll) distribution behavior upon "partial loading provides the primary measure of the extent of HDDNS aggregation.. To interpret this data, we employed slope-analysis methods reported by others (2. [13][14][15][16], but we were particularly interested in exploring the utility of the general least-squares approach represented by the programs SXLSQ (17) and…”

“…Earlier studies (Little and Singleterry, 1964;Van Dalen et al, 1974) showed that a small number of HD surfactant molecules participate in each reverse micelle, about 7-15. These small reverse micelles have a low molar ratio of water to HD, W0, in the micellar phase.…”
