style="text-indent:25px">靶向改性材料是正在被開發(fā)的可從混合物中選擇性移除所需組分或者從產品流、工藝流和廢水中移除0和/或高價值的金屬或化合物的高新技術之一。功能化材料的使用方式是將液體流經功能化材料、目標組分即被選擇性地去除。活性炭就是一種功能化材料。根據不同的工藝條件，活性炭的表面含有若干含氧有機基團。盡管活性炭的價格便宜，但是卻有許多缺點，如造成產品的大量流失并且無法有效去除**終產品中不需要的化合物或金屬至較低殘留量。這是由于活性炭的鍵合性質為非特異性鍵合，且其表面的醇、苯酚、醛和羧酸官能團功能性較差。山西食品中除鎳自然造就了大量的化合物和組分，被用于食品、生物制藥等行業(yè)，而其中的凈化就需要無錫定象這樣的專業(yè)企業(yè)。</p><div

style="text-indent:25px">去除水體中砷的技術主要有物理法、化學法和生物法等3類。其中，吸附是一種簡單易行的物理和化學除砷技術，適用于大規(guī)模水體的處理。常使用的吸附材料有氧化鐵、活性氧化鋁、沸石、活性炭、錳礦、粉煤灰等?；钚蕴烤哂胸S富的孔隙結構和獨特的化學官能團，是環(huán)境友好型優(yōu)良吸附劑。但普通活性炭比表面積小、孔徑分布寬和吸附選擇性差，需通過改性使其表面微孔結構或化學官能團改變，從而具有特殊的吸附和催化性能而應用于實際。近年來的研究發(fā)現，納米二氧化鈦具有很強的吸附砷的能力，但直接應用納米二氧化鈦作為污染水體中砷的吸附劑，一方面實際操作和回收極為困難，另一方面高純度的納米二氧化鈦產品價格高昂。為此筆者研究了一種讓活性炭負載納米二氧化鈦的方法，用于吸附廢水中的砷，可極大提高活性炭對廢水中砷的去除率。</p><p style="text-indent:25px">將其與納米二氧化鈦(粒徑15nm/粒徑100nm)、碳酸鈣、三氧化二鐵、活性碳、沸石、蒙脫土進行固定效果做對比。主要結果如下:(1)對ACTI和ACT的表征結果表明:ACT和ACTI的BET比表面積大,體積顆粒小。經過改性的材料表面粗糙,分散度好、孔徑分布窄,且成功負載納米TiO_2和Fe_2O_3。紅外表征結果表明兩種物質中都存在羥基和Ti-O鍵,ACTI中出現了Fe-O鍵。(2)添加ACTI、ACT、T-15和Fe_2O_3處理后,紅壤、紫色土和中性土的pH增加、銨態(tài)氮含量上升、硝態(tài)氮含量下降;酸性土pH增加、銨態(tài)氮含量上升、硝態(tài)氮含量上升;鈣質土pH下降、銨態(tài)氮含量下降、硝態(tài)氮含量下降;黑土pH下降、銨態(tài)氮含量上升、硝態(tài)氮含量下降。添加材料處理后紅壤、酸性土、鈣質土和紫色土的pH為中性,中性土偏堿性,黑土偏酸性。減少鉛對人類的侵害，是一項世界性的綜合課題。</p><div

style="text-indent:25px">礦山開發(fā)、金屬冶煉、工礦企業(yè)生產等活動產生大量重金屬廢料，以及工業(yè)“三廢”的不合理排放，使得重金屬進入生態(tài)環(huán)境導致空氣、土壤及水體受到污染，是造成食品重金屬污染的主要途徑。據統(tǒng)計，全世界每年消耗的鉛約有400萬噸，鎘消耗量約為2萬噸，汞消耗量約為1萬噸，砷消耗量約為2. 4萬噸，這些重金屬只有少量被回收利用，其余大部分以各種形式被排放到環(huán)境中造成污染。我國因工業(yè)“三廢”和污水灌溉已造成有70%的水域面積存在不同程度的污染，汞、鎘、鉻、鉛、砷等重金屬污染的耕地面積約已占我國耕地總面積的1/5，全國每年因重金屬污染而減產糧食1000多萬噸。通過無錫定象產品作業(yè)的物質，可使其中的鉛砷鎳鉻鎘等達到國標、歐標以上。陜西食品除鎳</p><p

style="text-indent:25px">硅膠吸附劑透明顆粒/變色顆粒，無害無味無污染，吸附性能高，不被人體吸收，對人體無害，誤食可經糞便排出，是一種傳統(tǒng)的吸潮除濕包裝封存產品。硅膠可分為細孔球形硅膠和細孔塊狀硅膠兩種。細孔球形硅膠外觀為無色或微黃色的透明或半透明球形顆粒，細孔塊狀硅膠為無色或微黃色半透明玻璃狀的不規(guī)則顆粒。細孔硅膠又叫A型硅膠。其通常是用硅酸鈉和H2SO4反應,并經老化，酸泡等一系列后處理過程而制得。硅酸屬于非晶態(tài)物質,其化學分子式mSiO2.nH2O。不溶于水和任何溶劑。無害無味，化學性質穩(wěn)定，除強堿、氫氟酸外不與任何物質發(fā)生反應。各種型號的硅膠因其制造方法不同而形成不同的微孔結構。硅膠的化學組織和物理結構，決定了它具有許多其它同類材料難以取代的特點：吸附性能高、熱穩(wěn)定性好、化學性質穩(wěn)定、有較高的機械強度等。山西食品中除鎳</p><p
