The dosage of modified carbon, methylene blue concentration, adsorption time, temperature, solution pH, and shaker speed were taken as investigation factors and methylene blue adsorption as investigation index, the Plackett-Burman (P-B) design was used to screen out the factors of significant effects. And further combined with the Box-Behnken Design (BBD) response surface method, the significant factors were optimized and verified and analyzed to obtain the optimal adsorption process parameters. The results showed that among the selected 6 factors, the order of significance affecting the adsorption capacity of methylene blue was modified carbon dosage > methylene blue concentration > shaking table rotation speed. The interaction effect between the significant factors was as follows: dosage of modified carbon and rotating speed of shaking table > dosage of modified carbon and concentration of methylene blue > concentration of methylene blue and rotating speed of shaking table. After optimization, the optimum adsorption conditions were obtained as follows: the dosage of modified carbon was 45.40 mg, the concentration of methylene blue was 86.00 mg/L, and the rotating speed of the shaking table was 130 r/min. Under these conditions, the adsorption capacity of methylene blue could reach 41.03 mg/g, the difference between the verified value and the model predicted value of 42.24 mg/g was 2.87%, therefore, the P-B/BBD method is stable and effective in optimizing the adsorption process of modified biochar for methylene blue, which provides a data reference for optimizing the adsorption process of carbon materials., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=MRfN1ZT1znN/qdoyq4Nmeg==, pdfFileSize=2501016, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.
