WebMay 1, 2024 · The fabric was pre-mordanted with FeSO4 and dyed with the turmeric extract at pH 7 and a material liquor ratio (MLR) of 1:20. Pseudo first-order and pseudo second-order kinetics were tested. The adsorption kinetics of turmeric extract dyeing on silk fit the pseudo second-order kinetic model. The activation energy was 94.9 kJ/mol. Web2.2.2 FIRST ORDER KINETICS We will start by considering the elementary reaction → The rate law can be given by − =𝑘 Integrating this expression yields −∫ 1 0 =𝑘∫ 0 which becomes −ln( 0 )=𝑘 and thereby = 0 −𝑘 and a plot of ln( ) vs. should be linear for first order kinetics. The half-life can be given by 1 2

You can calculate only k1 from this equation because qe is known to you from batch … WebAbstract. There is evidence that, for a number of chemicals, the elimination characteristics during bioconcentration do not follow monophasic first-order kinetics. In the first part of the present communication, a simple mathematical formula is presented that allows a clear-cut distinction between monophasic (pseudo-) and first-order and ... dove theater
