Adsorption Studies of I-Naphthaleneacetic Acid and 2,4-Dichlorophenoxyacetic Acid on Activated Carbon in Aqueous Solution and Oil Palm Tissue Culture Media

A study on the adsorption of activated carbon on oil palm culture media was carried out in two main parts, the adsorption of plant growth regulators I-naphthaleneacetic acid (NAA) and 2,4-dichlorophenoxyacetic acid (2,4-D) and root initiation of oil palm tissue culture. Four commercially availabl...

The adsorption of NAA and 2,4-D at different concentrations increased rapidly at the initial stage and then followed by a slower uptake until the equilibrium is established in 40 and 30 minutes. respectively. The maximum uptake was achieved at higher concentration for both of the plant growth regulators. The higher maximum uptake was obtained for higher surface area of the activated carbons.

On the other hand, Freundlich equation was slightly better fitted to the adsorption of NAA for other activated carbon samples.

Adsorption isotherm of 2,4-D showed that the Langmuir equation isotherm was better fitted to the experimental data for AC 1 and AC3, but AC2 and AC4 are better fitted to the Freundlich equation.
