The application of almond shell as a low cost natural adsorbent to remove Hg(2+) from aqueous solution was investigated. Batch experiments were carried out to evaluate the adsorption capacity of the material. The chemical and physical parameters such as pH, sorbent amount, initial ion concentration, and contact time were optimized for the maximum uptake of mercury onto the solid surface. Adsorption isotherms were expressed by Langmuir and Freundlich adsorption models, and the experimental data were found to fit the Langmuir model rather than the Freundlich. The maximum adsorption capacity obtained from the Langmuir isotherm was 135.13 mg/g. A kinetic study was carried out with pseudo-first-order and pseudo-second-order reaction equations and it was found that the Hg(2+) uptake process followed the pseudo-second-order rate expression. The thermodynamic values, ΔG(0), ΔH(0) and ΔS(0), indicated that adsorption was an endothermic and spontaneous process. The potential of this material for mercury elimination was demonstrated by efficient Hg(2+) removal from a synthetic effluent.

Banking industries in Iran is recently more competitive than last decade which may result of Private bankers' presence as well as modification performed in governmental bankers' plan. In fact the philosophy of these new strategies it is seeking for value creation in organization which obviously associate with innovation. The main aim of present research is to provide banker's emerging strategy using Blue ocean solution within Pasargad Bank of Iran. The current study is accomplished based on descriptive – analytical method and collection of required data has been implemented through designed questionnaire. Then, utilizing QSPM matrix, most attractive strategies prioritized (such as creation variety of services providing travelling banking services and enhance productivity, as well as to offer CCDM [CHECK/CASH DEPOSIT MODULE], increase in security and reduce misuse of related information, implement of updated software, establish a system to update expiration date of credit cards, and online payment of other currencies).
