This standard applies to the wet gold extraction process used in the coconut shell activated carbon adsorption capacity and the rate of determination, for activated carbon adsorption gold Can be evaluated.

2 terms and definitions

The following terms and definitions apply to this document. 2.1 Freundlich adsorption isotherm Freundlichadsorptionisotherm At a constant temperature, the relationship between the amount of adsorbed components per unit mass of adsorbent and the equilibrium concentration of the component is in accordance with Freundlich Adsorption equation, see equation (1). Q = kc n or lgQ = nlgc lgk (1) Where. Q - the amount of adsorbed components per unit mass of adsorbent when adsorbed equilibrium; c - the concentration of the adsorbed component at the time of adsorption equilibrium; k, n - constant. 2.2 Adsorption capacity The amount of adsorbent per unit mass of adsorbent for a given component in a fluid or fluid mixture at a given temperature, concentration or pressure. This standard Quasi-medium, activated carbon adsorption gold capacity refers to the adsorption equilibrium in the gold concentration of 1.0μg/mL unit mass of activated carbon adsorption of gold. 2.3 Adsorption rate At a given temperature, concentration or pressure, the amount of adsorbent adsorbed per unit of time for a given component. In this standard, the activity The carbon adsorption rate of carbon refers to the amount of adsorbed gold per unit mass of activated carbon adsorbed for 60 min in a solution with a gold concentration of 10.0 μg/mL. Determination of Adsorption Gold Capacity 3.1 Method Summary In the constant temperature conditions, the sample in a certain concentration of gold-containing solution to achieve adsorption equilibrium, the atomic absorption spectrometry determination of adsorption liquid Gold concentration, drawn Freundlich adsorption isotherm, calculated by the activated carbon adsorption gold capacity. 3.2 Reagents Unless otherwise stated, analytical pure reagents and deionized water or comparable purity of water are used in the analysis. 3.2.1 sponge gold. mass fraction ≥ 99.99%. ......
