大孔樹脂是由聚合單體和交聯(lián)劑、致孔劑、分散劑等添加劑經(jīng)聚合反應(yīng)制備而成的離子交換樹脂；聚合物形成后，致孔劑被除去，在樹脂中留下了大大小小、形狀各異、互相貫通的孔穴，因此大孔樹脂在干燥狀態(tài)下其內(nèi)部具有較高的孔隙率，且孔徑較大，在100-1000nm之間，故稱為大孔吸附樹脂。<br />大孔樹脂型號(hào)_大孔樹脂的類型：<br

/>3、大孔樹脂被吸附質(zhì)(溶液)上柱前應(yīng)經(jīng)除雜、過濾、澄清處理，盡量避免雜質(zhì)進(jìn)入樹脂柱，以免造成樹脂急性中毒，影響使用。<br />4、樹脂中斷使用，應(yīng)水洗干凈后，凈水浸泡存放，并須定期換水，以防受污染。亦可浸泡在飽和食鹽水或乙醇中長(zhǎng)期存放。<br />包裝：20kg桶<br />含水量<br />65-75%<br

在交換柱或提取器內(nèi)加入高于樹脂層10cm的95%以上的乙醇浸漬4小時(shí)，然后用蒸餾水淋洗至流出液在試管中用水稀釋不渾濁時(shí)為止。后用水反復(fù)洗滌至乙醇含量小于1%或無明顯乙醇?xì)馕都纯伞渲瑢用嫔媳３?-5mm液體，以免干柱。備用。<br />b) 新離子交換樹脂用2-4BV的95%以上的乙醇或甲醇以1～2BVhr的速度過柱(如有氣泡產(chǎn)生，須趕出氣泡)，然后用蒸餾水以1～2BVhr的速度淋洗至流出液在試管中用水稀釋不渾濁或無明顯乙醇?xì)馕稌r(shí)為止，樹脂層面上保持2-5mm液體，以免干柱。備用。<br />2、大孔樹脂過柱：<br />將要處理的原液以1-4BVhr的流速通過交換柱，樹脂層中不能有氣泡，(實(shí)驗(yàn)用交換柱要求樹脂裝填高徑比>3，生產(chǎn)中建議樹脂裝填高度2米左右，吸附流速1-4BVhr。)檢測(cè)流出液中目的產(chǎn)物的泄漏量，泄漏量達(dá)到進(jìn)口濃度的10%時(shí)，為吸附終點(diǎn)。<br />3、大孔樹脂解吸：<br />用1-2BV的蒸餾水置換出樹脂層中的原液，根據(jù)不同需要可用適量蒸餾水洗滌樹脂層。用乙醇或甲醇等有機(jī)溶劑以1-2BVhr的速度通過樹脂層,以洗脫目的產(chǎn)物,收集洗脫液,即為濃縮了的目的產(chǎn)物。<br />4、大孔樹脂再生：<br />當(dāng)大孔樹脂正常使用一定周期后，吸附能力降低或受急性嚴(yán)重污染時(shí)，需要強(qiáng)化再生處理，其方法是加入高于樹脂層10-20厘米的3-5%鹽酸溶液浸泡2-4小時(shí)后，用同樣濃度5-7倍體積量鹽酸溶液淋洗，再用凈水充分淋洗，直至出口洗滌液PH值呈中性，然后以5%氫氧化鈉溶液按以上方法浸泡2-4小時(shí)，并用同樣方法淋洗至通完5-7倍體積量氫氧化鈉溶液，再用水充分淋洗直至出水PH值呈中性，即可再次投入使用。<br />5、大孔樹脂強(qiáng)化再生方法：<br />當(dāng)樹脂使用一定周期后,吸附能力降低或受污染嚴(yán)重時(shí)需強(qiáng)化再生，其方法是在容器內(nèi)加入高于樹脂層10cm的3-5%鹽酸溶液浸泡2-4小時(shí)，然后進(jìn)行淋洗過柱。繼用3-4BV同濃度的鹽酸溶液過柱,然后用純水洗至接近中性;再用3-5%的氫氧化鈉溶液浸泡4小時(shí)。后淋洗過柱,用同濃度的3-4BV氫氧化鈉溶液過柱，后用純水清洗至PH值為中性,備用。<br />6、大孔樹脂使用時(shí)參考指標(biāo)：<br />項(xiàng) 目<br />參考值<br />使用溫度°C<br />150<br />吸附流速<br />1---4BVhr<br />解吸流速<br />0.6—2BVhr<br />解吸劑用量<br />2—3BV<br />解吸劑品種<br />乙醇或乙醇水溶液<br />再生液濃度<br />HCl：3-5%；
