There are very chemical reactions with very slow rates which can be catalyzed by enzymes. These biocatalysts need to moderate conditions for their catalytic activity and are stable in low temperature (between 15–50°C), average pH (5–10) and aqueous media. One of important things in enzymatic synthesis which has been recently noticed is the yield of reactions. Nowadays wide application of response...
Adsorption of Reactive Black 5 (RB5) and Reactive Orange 16 (RO16) from their binary mixture using MgA-NO3 -layered double hydroxide (MgAlNO3-LDH) was conducted in a batch system. First order derivative spectrophotometric method was used for simultaneous analysis of RB5 and RO16 in binary mixtures. The effect of pH, contact time, and initial concentration were investigated. The results of these analyses...
An anionic MgAlNO3 layered double hydroxides (MgAlNO3-LDH) with Mg/Al molar ratio 4∶1, was investigated for its ability to adsorb an anionic dye, Reactive Orange 16 (RO16), with the objective of evaluating its suitability as an adsorbent. The experimental data were analyzed by the Langmuir and Freundlich adsorption models. Equilibrium data fitted well with Langmuir model for the concentration range...
