有效鈣、鎂的測定（一）方法原理溶液中鈣、鎂離子測定同樣采用原子吸收光譜法進行，其基本原理同銅、鐵、錳、鋅等的測定。但與它們不同的是，溶液中的鈣、鎂離子容易與P、Al、Si、S及其它陰離子形成穩(wěn)定化合物，這些化合物不能在火焰上部分分解或不同全部分解，這樣就會減少參與吸收或發(fā)射的被測元素的原子數(shù)目，所以在測定過程中往往加一些釋放劑，其作用是讓釋放劑與干擾的陰離子進行反應(yīng)來阻止它與被測元素共同開成的穩(wěn)定化合物。在鈣、鎂離子的測定中，主要使用鑭鹽或鍶鹽作為釋放劑。（二）試劑配制1％鑭溶液稱取59gLa2O3放入1000mL燒杯中，加入約50mL水，然后小心加入250mL濃HCl，使之溶解。注意加HCl時動作一定要慢，并把燒杯放在冷水中冷卻，否則溶液會沸騰溢出，后面定容至5L。該試劑為抗干擾劑，也可用氯化鍶溶液代替。（三）操作步驟用加液稀釋器吸取1mL濾液，加9mL水,10mL1％鑭溶液，混勻，用原子吸收分光光度計測定Ca、Mg含量。同時作標準曲線。兩種元素均采用空氣－乙炔火焰，在鈣測定中，波長為，狹縫寬，其線性范圍為；在鎂測定中，波長為，狹縫寬，其線性范圍為。（四）結(jié)果計算式中：M為土壤有效鈣、鎂含量，單位為mg/L。C為待測液中有效鈣、鎂濃度。 </p><p> 石灰中有效氧化鈣含量的測定：石灰中有效氧化鈣及其它鈣是指游離狀態(tài)的氧化鈣，它不包括石灰中的碳酸鈣、硅酸鈣及其它鈣。石灰的優(yōu)劣品質(zhì)依有效氧化鈣含量而定，質(zhì)量石灰氧化鈣含量應(yīng)達到95%，而低質(zhì)的*為50%以下，工業(yè)用的應(yīng)達到60%。<span style="font-size:12px;">石灰中的有效氧化鈣，簡稱“有效鈣”，是指能迅速水解形成氫氧化鈣的、具有活性的那部分氧化鈣。由于煅燒溫度的原因，有的氧化鈣遇水后并不能迅速發(fā)生水解反應(yīng)，仍然以游離的氧化鈣形態(tài)存在，這種游離在水中的氧化鈣又稱為過燒氧化鈣；此外，石灰中一般還含有少量的硅酸鈣、鋁酸鈣、鐵酸鈣等鈣的化合物，他們都屬于非活性的鈣鹽，因此都不屬于有效鈣。</span>

石灰石是常見的一種非金屬礦產(chǎn)。我國石灰石礦產(chǎn)資源豐富,占世界總儲量的64%以上,是一種具有優(yōu)勢的天然資源。石灰石生成輕質(zhì)碳酸鈣后仍然用途多多：可用作橡膠、塑料、造紙、涂料和油墨等行業(yè)的填料。用于有機合成、冶金、玻璃和石棉等生產(chǎn)中。還可用作工業(yè)廢水的中種劑、胃與十二指腸潰瘍病的制酸劑、酸中毒的***劑、含SO2廢氣中的SO2消除劑、乳牛飼料填加劑和油毛氈的防粘劑。也可用作牙粉、牙膏及其它化妝品的原料。石灰石生產(chǎn)***造紙用涂布級重質(zhì)碳酸鈣產(chǎn)品。這類高附加值的微細、超細及活性重質(zhì)碳酸鈣在造紙工藝中應(yīng)用十分***,粉碎后一般粒徑-2μm≥90%的用于中性施膠造紙工藝;-2μm粒徑≥50%的主要用于涂布紙的填料。高鈣石灰石經(jīng)高溫煅燒后可以生成***冶金石灰，在鋼鐵精煉過程中可以發(fā)揮很好的脫硫作用，是一種非常好的冶金輔料，在特種鋼鐵生產(chǎn)中可以起到很好的脫硫作用，高鈣石灰石的優(yōu)點很多，在工業(yè)應(yīng)用發(fā)面還有很好的前景，值得我們研究。有效氧化鈣大于等于氧化鈣含量，氧化鈣含量是生石灰的綜合分析。浙江雙梁有效鈣設(shè)備</p><p
