... technology, TG test and DSC test. The organic components in the soil surrounding the PE gas pipe failure area were qualitatively identified. Findings The results showed that the organic surfactants in the soil environment could accelerate the aging behavior of PE material, leading to a deterioration...

... implications The determination of change of Pb⁺⁺ concentrations was carried out using a Perkin‐Elmer atomic absorption Spectrophotometer. Originality/value The rate of PbII/Zn cementation reaction in the presence of surfactants as non‐ionic (Triton‐X‐100), anionic (SDS) and cationic (CTAB...

...G. Bereket; M. Gülec; A. Yurt Purpose The purpose of this paper is to investigate the inhibiting properties of six quaternary ammonium salts, three cationic surfactants and two non‐ionic surfactants in 2 M KOH. An attempt also was made to correlate some molecular parameters of these compounds...

...Dong Youp Ryu; Michael L. Free Purpose To evaluate mild steel corrosion using a new surfactant‐inhibition model which was derived, in part, from the concept of intermolecular energy and molecular separation distance. Design/methodology/approach A Gamry potentiostat was used for polarization...

...N.A.F. Al‐Rawashdeh; A.K. Maayta Purpose To investigate the inhibiting effect of the cationic surfactant cetyl trimethylammonium chloride (CTAC) on aluminum (Al). Design/methodology/approach Pure aluminum rods were immersed in hydrochloric acid (HCl) and sodium hydroxide (NaOH) solutions...

...S. Tamilselvi; S. Rajeswari The inhibitive action of triazoles and surfactants on the corrosion of carbon steel has been studied using the weight loss method and electrochemical studies. Results obtained show that these organic compounds are very good inhibitors. Potentiodynamic polarisation...

...P. Manjula; S. Manonmani; P. Jayaram; S. Rajendran The inhibition efficiency of N‐cetyl‐N,N,N‐trimethylammonium bromide (CTAB), a cationic surfactant, in controlling the corrosion of carbon steel in an aqueous solution containing 60ppm Cl^–, in the absence and presence of Zn²...

... act as inhibitors in the acid environment. The adsorption and inhibition efficiency are discussed as a function of the concentration and the nature of mixing the two surfactants. T₈₀ + α_SOS mixtures show a better inhibition effect than SOS + α_T80, that increases...

...D. Gopi; N. Bhuvaneswaran; S. Rajeswarai; K. Ramadas Some thiourea derivatives, non‐ionic surfactants and their synergism when used simultaneously were evaluated for their efficiency as corrosion inhibitors for mild steel in 1N H₂SO₄ solution at different temperatures (303...

...S. Rajendran; B.V. Apparao; N. Palaniswamy The influence of a cationic surfactant, N‐cetyl‐N, N, N‐trimethyl ammonium bromide (CTAB) on the inhibition efficiency (IE) of calcium gluconate (CG) – Zn²⁺ system in controlling corrosion of mild steel in a neutral aqueous environment...

... on the volume per cent of PTFE were evaluated. Also several studies were carried out with aqueous surfactant mixture solutions including surface tension (γ), critical micelle concentration (CMC), micellar composition (X_m), activity coefficient (υ), micellar interaction parameter (β^m...

...Z. Abdel Hamid; T.Y. Soror; H.A. El‐Dahan; A.M.A. Omar The inhibiting effect of cationic surfactant N, N, N‐dimethyl 4‐methylbenzyl dodecyl ammonium chloride on mild steel in hydrochloric acid solutions was investigated by surface and thermodynamic measurements, weight loss tests, polarization...
