This letter is a response to the comment by Professor Ho on our recent article entitled "Acid Green 25 removal from wastewater by organo-bentonite from Pacitan" published in Applied Clay Science 48 (2010) 81-86. Professor Ho raised an issue about citation misleading for the pseudo-first and second order kinetic equations which are widely used to correlate kinetic adsorption data. This letter is intended to clarify the misunderstanding and present the correct citations. © 2010 Elsevier B.V.
