Abstract
วัสดุจีโอโพลิเมอร์พรุน (Porous geopolymer) จากเถ้าทิ้ง (Waste ashes) สำหรับปรับสภาพ นํ้าเสียที่มีฤทธิ์เป็นกรดสูง ประกอบด้วยเถ้าทิ้ง (Waste ashes) ที่มีสมบัติความเป็นสารปอซโซลานตํ่า (Low pozzolan) กรดบอริก (Boric acid H3BO3) โซเดียมโบคาร์บอเนต (Sodium bicarbonate) สารละลายโซเดียมซิลิเกต (Sodium silicate Na2SiO3) และสารละลายโซเดียมโฮดรอกไซด์ (Sodium hydroxide NaOH) ที่มีความเข้มข้น 8 10 โมลาร์ (Molar M) โดยผสมส่วนผสมทั้งหมดให้เป็นเนื้อ เดียวกัน แล้วเทของผสมที่ได้ลงในแบบหล่อ บ่มด้วยความร้อน จะได้เป็นวัสดุจีโอโพลิเมอร์พรุน (Porous geopolymer) ที่แข็งและพองตัว ซึ่งนำไปทุบให้มีขนาดเล็กและร่อนผ่านตะแกรง จะได้วัสดุจีโอโพลิเมอร์ พรุน (Porous geopolymer) ที่มีฤทธิ์เป็นเบส นำไปใช้ปรับสภาพนํ้าเสียที่มีฤทธิ์เป็นกรดสูง ให้มีค่าพีเอช (pH) อยู่ในช่วง 5.5 9.0 Porous geopolymer material from waste ashes for conditioning Wastewater that is highly acidic It consists of waste ashes that have low pozzolan properties, boric acid (Boric acid H3BO3), sodium bicarbonate (Sodium bicarbonate), sodium silicate solution (Sodium silicate Na2SiO3) and sodium solution. Hydroxide (Sodium hydroxide NaOH) with a concentration of 8 10 molar (Molar M) by mixing all the ingredients into a homogeneous state and then pouring the resulting mixture into the mold. Cured with heat The result is a porous geopolymer material that is hard and swollen. which is pounded into small sizes and sieved through a sieve You will get a porous geopolymer material that has a base effect. Used to condition highly acidic wastewater. To have a pH value (pH) in the range 5.5 - 9.0
