“…The methods of kinetic experiments are mainly similar to those of equilibrium tests. The aqueous samples were collected at regular periods, and the concentrations of dye were measured in the same manner [11]. q t (mg/g) (the amount of adsorption at time t) was calculated as follows:…”

“…where C 0 , C t , and V represents the concentration of dye (mg/L) in liquid-phase at initial, concentrations of dye (mg/L) in liquid-phase at any time and volume of the solution (L), respectively. W is the weight of dry adsorbent (g) [11].…”

“…The linearized form of isotherms models and their constants parameters that have been obtained from the slope and intercept of the plots (were shown in Fig. 3((a), (b), (c), (d) at 310.15 K) have been given in Table 1 [7,11,32]. The correlation coefficient (R 2 ) in Table 1, demonstrates that the Freundlich model has the most satisfying fit with the experimental data and the Langmuir isotherm model has the least correspondence.…”

“…This process is widely applied in order to treat continuously aqueous wastes produced by industrial processes. This procedure has been perceived to be highly capable and effective for the removal of dyes in terms of low operational cost, the simpleness and convenience of design, operation easiness, high efficiency, insensitivity to toxic substances, and the reusability of adsorbents [2,11,21]. Adsorbents are abundant and mostly inexpensive such as alumina, zirconium, diatomaceous earth, activated carbon, cellulose, and the different types of silicates.…”

The present research introduces adsorption of sulfonated cobalt phthalocyanine catalyst (Europhtal) from the real wastewater that is produced by the mercaptan removal unit (Merox) of the third refinery, South Pars Gas Complex (SPGC), Assaluyeh, Iran. Therefore, novel low-cost natural zeolite modified with polyaluminium chloride (PAC) was investigated as an adsorbent for the treatment of Europhtal wastewater. Central composite design (CCD), as a set of response surface methodology (RSM), was applied to acquire optimum operational conditions such as contact time, pH, adsorbent dosage, and Europhtal concentration. Results showed that the removal percentage of Europhtal in the real wastewater was 93.4% at best operating condition consisting of a pH of 6.7, sonication time of 8 min, 0.035 g of adsorbent. The obtained results were evaluated by adsorption isotherms and kinetic parameters. It was found that the equilibrium data matched the Freundlich model acceptably, with the maximum experimental adsorption capacity of this model was 687.51 mg g-1 at 301.15 K. From the kinetic data, it was revealed that the adsorption process followed the pseudo-second-order kinetic model. Furthermore, the obtained thermodynamic parameters such as ∆H°, ∆S°, and ∆G° imply the endothermic essence of adsorption proceeding spontaneously.

Raw materials from some mines from the Iraqi Westren Desert were used to manufacture tap water porcelain filter. They were Montmorolinite clays, Sand, Limestone, and remnants of the membership. These materials were cleaned dried grind and sieved to the required size then several homogenous mixtures were prepaired using different amounts of the raw materials. Filter test samples were prepaired. Several testes were carried to get the porcelain propetrties. They were apparent density, apparent porosity, percentage of absorbed water, and hydraulic conductivity. Tests results of these properties showed that the addining of remnants of the membership has big effect on the porcelain properties and the changes of these properties depend on the amount of these additives in the porcelain body. As a result for these changes the amount of water which could be filtered by them would be increased respectly. These filters were compatible with important filter standard specifications such as toxicity test and suspended particles. The results showed that the filtered water were conformity with the specifications for public drinking water with high flow rates.
