“…Oleh karena itu, dalam preparasi nanopartikel dengan metode deposisi elektrokimia, penggunaan surfaktan sebagai aditif menjadi sangat penting karena, pada umumnya, partikel yang dihasilkan dengan metode ini tidak homogen dan memiliki ukuran ≥10 µm. Nilai CMC dapat ditentukan dari perpotongan dua garis lurus pada diagram konsentrasi surfaktan vs. salah satu dari fungsinya misalnya tegangan permukaan [4]. Dalam kajian ini, CMC kemudian ditentukan dari perpotongan dua garis lurus pada bagian yang bergantung kepada konsentrasi dengan bagian yang tidak bergantung kepada konsentrasi.…”

AbstrakSurfaktan dapat digunakan sebagai aditif yang dapat mengontrol dan memodifikasi proses pertumbuhan partikel yang dipreparasi dengan metode deposisi elektrokimia. Kajian pendahuluan terhadap pengaruh penggunaan surfaktan Glucopone 215 CSUP terhadap karakteristik elektrokimia elektrolit sulfat telah dilakukan menggunakan teknik cyclic voltammetry. Hasil pengukuran menggunakan tensiometer menunjukkan bahwa ion-ion dari elektrolit tidak menimbulkan perbedaan signifikan terhadap critical micelle concentration (CMC) surfaktan yang dikaji. Pengaruh penambahan surfaktan Glucopone 215 CSUP terhadap cyclic voltammogram teramati ketika konsentrasi surfaktan diatas nilai CMC-nya. Katodik scan dari cyclic voltammogram menunjukkan bahwa pada konsentrasi diatas surfaktan, 1,3 wt.%, titik kenaikan arus katodik bergeser ke potensial yang semakin negatif. Hasil ini memberikan informasi potensial co-electrodeposisi yang sesuai untuk Co, Ni, dan Cu yang dipreparasi dari elektrolit sulfat dengan menggunakan aditif Glucopone 215 CSUP.

The cellulose derivatives solutions in the presence of surfactants have been investigated by the enhanced Rayleigh scattering (ERS) technique. The ERS experiments yield different information on the aggregate formation of cellulose derivative/surfactant in aqueous solution on the basis of theory of ERS. The results indicated that the ERS intensity of polymer/ surfactant system changes in different ways with continuing addition of surfactant. The critical aggregate concentration of cellulose derivative/surfactant systems is easy to determine. The change of ERS intensity reveals the aggregate formation of polymer/ surfactants and the shrinking state of polymer chains in evidence. Accordingly, ERS is a potent technique to study the cellulose derivative solutions in the presence of surfactants due to its simplicity, rapidity and sensitivity.

“…However, Rayleigh scattering will deviate from the law and the intensity of some wavelengths will rapidly increase if the wavelength of the incident beam is close to that of the absorption band of the aggregated molecular particles. Recently, RLS has become a useful technique for the determination of traces of inorganic ions [10,11], nucleic acids [12,13], surfactants [14,15], drugs [16][17][18] and proteins [19,20], as well as for the studies of interactions of biopolymers with their probes [21].…”

ABSTRACT. A novel method of chemistry applicable to the determination of trace lead in water samples based on the resonance light scattering (RLS) technique has been developed. In dilute phosphoric acid medium, in the presence of a large excess of I -, Pb(II) can form [PbI4] 2-, which further reacts with tetrabutyl ammonium bromide (TBAB) to form an ion-association compound. This results in significant enhancement of RLS intensity and the appearance of the corresponding RLS spectral characteristics. The maximum scattering peak of the system exists at 402 nm. Under optimum conditions, there is a linear relationship between the relative intensity of RLS and concentration of Pb(II) in the range of 0.04-1.8 µg/mL for the system with a low detection limit of 0.74 ng/mL for Pb(II). Based on this fact, a simple, rapid, and sensitive method has been developed for the determination of Pb(II) at nanogram level by RLS technique using a common spectrofluorimeter. This analytical system was successfully applied to determining trace amounts of Pb(II) in water samples that agree well with the results by atomic absorbance spectrometry (AAS).
