“…Results indicated that TECAM quickly and efficiently accumulated hydrophobic organochlorine pesticides (OCPs) from water. Semi-permeable membrane devices (SPMD), which are based on the diffusion of hydrophobic substances from water to membrane bags filled with lipophilic phases, are widely used for monitoring organic contaminants in water (Huckins et al, 1990;Lu et al, 2002;Lu and Wang, 2003;Frank, 2005). Recently, a novel composite absorbent, triolein-embedded sorbent, is proposed for selectively removing trace POPs from water (Ru et al, 2007a(Ru et al, , 2007bHuo et al, 2005aHuo et al, , 2005bLiu et al, , 2007.…”

As an effective, efficient, and economic approach for water purification, adsorbents and adsorption processes have been widely studied and applied in different aspects for a long time. In the recent years, a lot of novel adsorption processes have been developed for enhancing the efficiency of removing the organic and inorganic contaminants from water. This article reviews some new adsorbents and advanced adsorption methods that specialize in their compositions, structures, functions, and characteristics used in water treatment. The review emphasizes adsorption/catalytic oxidation process, adsorption/catalytic reduction process, adsorption coupled with redox process, biomimetic sorbent and its sorption behaviors of POPs, and modified adsorbents and their water purification efficiency.

“…The trapping of chemicals in the passive sampling devices has been described as simple diffusion and partitioning between two compartments of the receiving phase and external environment separated by a diffusion-limiting membrane [4,10,11]. In order to have maximum sensitivity, a sampler design should have a high A/L ratio where A is the area and L is the length of the sampler.…”

“…A number of review papers [10][11][12][13][14] have been written on passive samplers for water monitoring indicating the growing interest in this area. However, aspects of the simplicity, selectivity and the need for passive samplers to consume less organic solvents have not been fully addressed.…”

“…The adsorbent is mainly composed of the supporting activated carbon and the surrounding triolein-embedded cellulose acetate membrane. Several researchers have found that triolein has a high accumulating capacity (10 5 -10 7 ) for trace lipophilic chemicals [10,11]. Moreover, triolein is naturally found in fatty tissue of animals, and so it is inexpensive to purchase and safe to use in adsorption procedures.…”

In this study, a novel triolein-embedded activated carbon composite adsorbent (CA-T) was prepared and applied for the adsorption and removal of dieldrin from aqueous systems. Experiments were carried out to investigate the adsorption behavior of dieldrin on CA-T, including adsorption isotherms, adsorption kinetics, the influence of initial concentration, temperature, shaking speed, pH and the addition of humic acid (HA) on adsorption. The adsorption isotherms accorded with Freundlich equation. Three kinetics models, including pseudo-first-order, pseudo-secondorder and intraparticle diffusion models, were used to fit the experimental data. By comparing the correlation coefficients, it was found that both pseudo-second-order and intraparticle diffusion models were used to well describe the adsorption of dieldrin on CA-T. The addition of HA had little effect on dieldrin adsorption by CA-T. Results indicated that CA-T appeared to be a promising adsorbent for removing lipophilic dieldrin in trace amount, which was advantageous over pure granular activated carbon (GAC). The adsorption rate increased with increasing shaking speed, initial concentration and temperature, and remained almost unchanged in the pH range of 4-8. Thermodynamic calculations indicated that the adsorption reaction was spontaneous with a high affinity and the adsorption was an endothermic reaction.
