Web(1) Hydroxyapatite (HAp), which can be obtained by several methods, belongs known to be a good adsorbent. Coal fly ash (CFA) is a commonly reused byproduct also used in environmental applications as the adsorbent. We sought to answer the following question: Can CFA be included in this method of HAp wet compound to produce a composite … WebRedlich-Peterson (REDLICH; PETERSON, 1959)(4) 1 ( )* β * * a C a C q +R = OBS.: (1) q MAX é a capacidade máxima de molécula que pode ser adsorvida no material.

WebRedlich–Peterson is an isotherm model; a combination of both Langmuir and Freundlich model equations. This isotherm is based on Equation 4 . (4) In Equation 4, A and B are the capacity and the equation constant, respectively. Also, “g” lies between 0 and 1. Web10. apr 2024 · Results show that increasing temperature leads to an increase in the adsorption capacity of both oxides. Studying the effect of pH at 4, 7 and 11 show that the maximum adsorption capacity of CuO is attained at pH 7. However, the Redlich-Peterson isotherm shows a better fit than both the Langmuir and Fruendlich isotherms.
