Topic : ขอวิธีกำจัดกรดกำมะถันค่ะ
จากคุณ : แอน [ 6/2/2010 6:34:57 PM]
แกลลอนใส่กรดกำมะถันที่อยู่ในตู้เหล็กเกิดรั้วค่ะ
พอมาเห็นอีกที ก็กัดตู้จนทะลุแล้วกรดก็ไหลเต็มพื้นเลยค่ะ
เลยอยากรบกวนถามวิธีในการกำจัดกรดกำมะถันที่ถูกวิธีหน่อยค่ะ
ขอบคุณมากค่ะ

1. กั้นบริเวณบริเวณอาจใช้ทรายแห้ง
2. ปรับกรดให้มีค่า pH ให้เป้นกลางค่อยๆโปรย Calcium carbonateหรือปูนขาว ให้ทั่วพื้นที่ ระหว่างที่กรดสัมผัส calcium carbonate จะเกิดก๊าซ CO2 และความร้อนเกิดขึ้น ดังน้ันในพื้นที่นั้นต้องทำในตู้ควัน และสวมใส่ PPE
3. เมื่อควันลดลง คลุกเคล้าปูนขาวให้สัมผัสกรดมากที่สุด ถ้ายังคงเกิดก๊าซ ให้ค่อยเติมปูนขาวลงไป
4. Sulfuric acid + Calcium carbonate = Calcium sulphate (หรือยิปซัม) + CO2 + H2O

ใช้ทรายละเอียดซับ หรือถ้าหาไม่ได้ดินแห้งๆแถวนั้นก็ได้แต่อย่ามีเศษใบไม้เศษขยะอื่นๆติดมา นำมาซับแล้วตักใส่ถังพลาสติกแล้วค่อยไปปรับสเถียรอีกทีในที่โล่งๆกับปูนขาวพยายามเกลี่ยให้กว้างๆหน่อย รอดูว่าไม่มีปฏิกิริยาควันร้อนแล้วค่อยตักเอาไปกลบฝังอีกทีในสถานที่เหมาะสม แต่อย่าเอาไปทิ้งลงคลองเดี๋ยวโดนร้องเรียน คิดว่าคงไม่เยอะ ก็คงไม่ต้องส่งโรงงานรับกำจัดเปลืองตังค์...จบแค่นี้แหละ

“You http://www.officialreligionoutlet.com came—oh! http://www.moncleroutletstoreol.us Mr. http://canadagoosewsaleo.com Incledon, do not be angry—I want http://www.yeezysboost350ol.us to http://genuinbootsale.us tell http://www.nikerosherunol.us you everything.

You http://www.christianlouboutinups.com came; and mamma told me http://www.uggonlinestoreofficialol.us that http://www.pandoracharmsol.com same night. Oh, how http://www.kobe9nikesos.us frightened I was http://www.nikesoccerbootstore.us and miserable! Everything seemed to turn round with http://www.nikestoreolsale.com me. http://www.tomsoutletgon.us She said http://www.bootugguoutlet.us you loved me, http://www.longchampols.com and that you were very http://www.nikesaleol.top good and http://www.monclerstoreofficialoutlet.com very kind,—but http://www.tomsforsaleo.us that I knew,—and http://www.airjordanretrosaleol.com would do so http://www.nikehuaracheos.us much http://www.tomsonsaleo.online for the boys, http://www.nikeshoessalees.com and be http://www.nikestoreots.us a http://www.uggolcleance.us comfort http://www.candagooseoutletols.com and help to her in our http://www.conversesalestore.us great http://christianlouboutinfrsale.com poverty.” http://www.botasdefutboldesalida.com At http://www.huarachenikesale.us these words he stirred again http://www.bootcentreol.us and http://www.goodssaleol.com loosened, but did not quite http://www.tiendabotasdefutbolnike.com let go, http://www.coachfactorystoreol.us his grasp http://www.borlettoweb.com of http://www.pandoracharmbraceletol.com her http://www.uggoloutle.us hand. Rose http://www.airmaxboutiquefem.com was, http://www.nikeairmaxolo.us without knowing it, acting like http://www.adnmdstsaleo.com a skilful http://ajretro23outlet.com surgeon, http://www.airmaxverkaufende.com cutting deep http://www.officialmoncleroutletstoreo.com and sharp, that http://www.adyeezysaleot.top the pain http://www.nikepolosaleo.us might be over the sooner. He leaned http://www.monclersaleol.top his head http://fitflopofficialoutlet.com on his http://www.nikeairmax90ous.us other hand, turning http://www.pandoraolstore.com it away from http://www.nikeairpaschero.com her, and http://www.airmaxsalestoreol.us from time to http://www.abercrombiesolpstore.us time stirred http://www.itmksale.org unconsciously http://www.nikemaxpaschero.com when http://www.mksbagsaleol.com the http://www.jordans11retros.us sting http://www.adidasolsale.com was too much http://www.goosecanadaoloutlet.biz for http://tomsshoeswomenol.us him, http://pandoraocharms.us but did http://www.adsuperstarfr.com not http://www.tomsoutletsol.us speak. http://www.wintergoodsol.com “And http://www.nikeairmaxsalo.us she said more than this.

Mr. http://www.mkbagsalesoutletol.us Incledon dropped http://www.adidasnmdsaleo.top Rose’s http://www.mktotesol.com hand; http://bagsalemkol.us he turned http://www.adidasfluxol.com half away from her, http://www.zapatosnikeaires.com supporting his http://www.reebokshoesoutletol.us head http://www.adidasoriginalol.com upon both http://www.nikechaussurespaschero.com of his hands, so that she http://www.pandoraoutletofficialstore.com did http://www.ajlbkshoe.us not http://www.officialvansoutletstore.us see his http://www.sortiedemagasinnike.com face.
