Decolorization efficiency was optimized as a function of changes in process type, initial pH value, adsorbent concentration, temperature, reaction time, and initial dye concentrations of RY145 and RB19 based on response surface methodology (RSM) using Box-Behnken Design. The maximum decolorization efficiency of 99.9% for both RY145 and RB19 was obtained with ultrasound-assisted adsorption under the RSM-optimized conditions (with unity desirability) of 76.98 and 79.40 min reaction times, 233.20 and 254.29 mg L-1 initial dye concentrations, 1.37 and 1.44 g L-1 adsorbent concentrations, and 35.42 and 49.37 °C, respectively. The best-fit multiple non-linear regression models of decolorization efficiency with the highest adjusted coefficients of determination (R2adj) explained 99.52% and 99.48% of variations through adsorption of RY145 and RB19 and 98.14% and 98.01% of variations through UAA of RY145 and RB19, respectively, while artificial neural networks accounted for 99.82%.</p></abstract><publication_date><month>01</month><day>23</day><year>2018</year></publication_date><pages><first_page>14</first_page><last_page>24</last_page></pages><publisher_item><identifier id_type="pii">gnest_02240</identifier></publisher_item><doi_data><doi>10.30955/gnj.002240</doi><timestamp>1713551136</timestamp><resource>https://journal.gnest.org/publication/gnest_02240</resource></doi_data></journal_article></journal></body></doi_batch> </div>
