The results show that, increase the number of pore structure by modified agricultural and domestic waste surface, increasing the surface area, surface oxidation to form abundant oxygen containing functional group。 modified agricultural and domestic wastes on the adsorption capacity of methylene blue was significantly better than that of the unmodified waste. Finally through the 1mol/l of sodium hydroxide modified 60 corn stalk at 45 degrees Celsius for 8 pH conditions, adding reached the maximum adsorption of 100min. This experiment mainly for the control of experimental variables, and use the materials and visible spectrophotometer preprocessing. Keywords: corn stalk, high Na2O, methylene blue, adsorption rate 1 1 前言 目前,隨著社會(huì)的進(jìn)步和科學(xué)技術(shù)的發(fā)展,工業(yè)漸漸代替農(nóng)業(yè)成為國(guó)家發(fā)展的支柱產(chǎn)業(yè)。但工業(yè)的迅速發(fā)展也為我們生活的環(huán)境甚至整個(gè)地球帶來(lái)很大的危害。陽(yáng)離子染料亞甲基藍(lán)在水溶液中易于形成季銨鹽離子集團(tuán),通常應(yīng)用于染色,環(huán)境治理和監(jiān)測(cè),以及整個(gè)印染工業(yè)中。由于亞甲基藍(lán) 色度很高,大量排入水中污染嚴(yán)重,其實(shí)即使很少一部分進(jìn)入水中也會(huì)造成大面積水體著色,不僅影響水體顏色不美觀,更會(huì)對(duì)人類和地球整個(gè)生物群造成危害,影響光合作用。在人類創(chuàng)造經(jīng)濟(jì)財(cái)富的同時(shí),環(huán)境問(wèn)題也一直呈現(xiàn)著不同程度上的污染和地域上的蔓延。污染成為人類日常生活和生產(chǎn)中必須
