</p> <p> 在滿足公眾食品消費(fèi)需求的同時，其安全衛(wèi)生問題已成為嚴(yán)峻的社會問題，得到各國監(jiān)管者的高度重視。食品重金屬污染由于其毒性強(qiáng)、可蓄積、半衰期長等特性，不*成為**開發(fā)計(jì)劃署（UNDP）、**糧食及農(nóng)業(yè)組織（FAO）、世界衛(wèi)生組織（WHO）的全球食物污染物監(jiān)測計(jì)劃中的重要項(xiàng)目，也是我國目前食品污染領(lǐng)域重點(diǎn)監(jiān)測項(xiàng)目之一。 </p> <p> <br /> </p><p> 原材料無機(jī)靶向材料是一種高活性吸附材料，通常是用硅酸鈉和溶液反應(yīng)，并經(jīng)一系列后處理過程而制得。靶向材料屬非晶態(tài)物質(zhì)。不溶于水和任何溶劑，無害無味，化學(xué)性質(zhì)穩(wěn)定，除強(qiáng)堿、氫氟酸外不與任何物質(zhì)發(fā)生反應(yīng)。各種型號的靶向材料因其制造方法不同而形成不同的微孔結(jié)構(gòu)。靶向材料的化學(xué)組份和物理結(jié)構(gòu)，決定了它具有許多其它同類材料難以取代的特點(diǎn)：吸附性能高、熱穩(wěn)定性好、化學(xué)性質(zhì)穩(wěn)定、有較高的機(jī)械強(qiáng)度等，家庭用做干燥劑，濕度調(diào)節(jié)劑，除臭劑等；工業(yè)用作油烴脫色劑，催化劑載體，變壓吸附劑等；精細(xì)化工用分離提純劑，啤酒穩(wěn)定劑，涂料增稠劑，牙膏摩擦劑，消光劑等。靶向材料根據(jù)其孔徑的大小分為：大孔靶向材料、粗孔靶向材料、B型靶向材料、細(xì)孔靶向材料。由于孔隙結(jié)構(gòu)的不同，因此它們的吸附性能各有特點(diǎn)。粗孔靶向材料在相對濕度高的情況下有較高的吸附量，細(xì)孔靶向材料則在相對濕度較低的情況下吸咐量高于粗孔靶向材料，而B型靶向材料由于孔結(jié)構(gòu)介于粗、細(xì)孔之間，其吸附量也介于粗、細(xì)孔之間。無機(jī)靶向材料根據(jù)其用途，還可以分為啤酒靶向材料、變壓吸附靶向材料、醫(yī)用靶向材料、變色靶向材料、靶向材料干燥劑、靶向材料開口劑、牙膏用靶向材料等。改性二氧化硅及其生產(chǎn)與使用，如從產(chǎn)品流、工藝流和廢水中去除有機(jī)和無機(jī)化合物。</p><div
