บทคัดย่อ
ตัวดูดซับชนิดหนึ่งที่ถูกนำมาใช้อย่างแพร่หลายในการบำบัดน้ำเสียคือ ซิลิกาเจล งานวิจัยจำนวนมากศึกษาการผลิตซิลิกาเจลจากวัตถุดิบต่างๆ แต่ไม่ค่อยมีรายงานเกี่ยวกับการผลิตซิลิกาเจลจากหินแร่ภูเขาไฟ ดังนั้นงานวิจัยนี้จึงมีวัตถุประสงค์เพื่อ 1) ศึกษาสภาวะที่เหมาะสมในการผลิตซิลิกาเจลจากหินแร่ภูเขาไฟ โดยปัจจัยที่ศึกษาประกอบด้วย ชนิดของสารละลายด่าง[โพแทสเซียมไฮดรอกไซด์ (KOH) และโซเดียมไฮดรอกไซด์ (NaOH)] ความเข้มข้นของสารละลายด่าง (1, 2, 3 และ 4 โมลาร์) และอุณหภูมิ (70, 80 และ 90 องศาเซลเซียส) ที่ใช้ในการสกัดซิลิกาจากหินแร่ภูเขาไฟ และ 2) ศึกษาความสามารถของซิลิกาเจลจากหินแร่ภูเขาไฟในการกำจัดตะกั่ว (Pb2+) ในน้ำเสียสังเคราะห์ โดยปัจจัยที่ศึกษาคือ ระยะเวลาในการสัมผัส(30, 45 และ 60 นาที) จากผลการทดลองและการวิเคราะห์ทางสถิติ แสดงให้เห็นว่า สภาวะที่เหมาะสมที่สุดในการสกัดซิลิกาจากหินแร่ภูเขาไฟคือ ทำการสกัดด้วยสารละลายโซเดียมไฮดรอกไซด์ ความเข้มข้น 4 โมลาร์ ที่อุณหภูมิ 90 องศาเซลเซียสเป็นเวลา 3 ชั่วโมง ทั้งนี้ เนื่องจากที่สภาวะนี้สามารถสกัดซิลิกาออกจากหินแร่ภูเขาไฟได้มากที่สุด นอกจากนี้ ความเข้มข้นของซิลิกาที่สกัดได้จากสภาวะนี้ ยังแตกต่างจากที่สภาวะอื่นๆ อย่างมีนัยสำคัญยิ่ง (p<0.01) โดยร้อยละผลผลิตของซิลิกาเจลเท่ากับ40.25 จากรูปแบบการเลี้ยวเบนของรังสีเอกซ์บ่งชี้ว่า ซิลิกาเจลที่ผลิตขึ้นจากหินแร่ภูเขาไฟเป็นซิลิกาอสัณฐาน สำหรับผลการศึกษาความสามารถในการกำจัดตะกั่ว (Pb2+) ของซิลิกาเจลจากหินแร่ภูเขาไฟ พบว่า ซิลิกาเจลจากหินแร่ภูเขาไฟสามารถกำจัดตะกั่ว (Pb2+) ในน้ำเสียสังเคราะห์ได้มากถึงร้อยละ 89.52–92.67 โดยเมื่อระยะเวลาในการสัมผัสเพิ่มขึ้น ความสามารถในการกำจัดโลหะหนักจะเพิ่มขึ้น ซึ่งที่ระยะเวลาสัมผัส 60 นาที สามารถกำจัดตะกั่วในน้ำเสียสังเคราะห์ได้ร้อยละ 92.67
