Some reports indicate that heated sodium hydroxide is an excellent cleaning agent. When dissolving solid, gradually Sodium hydroxide causes skin to burn upon contact and will cause irrevocable damage if ingested. 1 M sodium hydroxide and 3 M sodium chloride, with a total contact time of one hour, effectively removes radiolabelled calf thymus DNA from a weak anion exchanger. Over the years, varied cleaning agents have been proposed. Sodium hydroxide is used to manufacture many everyday products, such as paper, aluminum, commercial drain and oven cleaners, and soap and detergents. Its hydrolyzing power is enhanced by the presence of chlorine. More recently, Q‑One Biotech Ltd. has made available its data on the ability of sodium hydroxide to inactivate eight different viruses. s�H!wx;ȉË�ކ���F�(�C����=d�s#�m�GuE��� �$eSRtfsȱa��% ʣ�5�� endstream endobj 92 0 obj 260 endobj 54 0 obj << /Type /Page /Parent 48 0 R /Resources << /ColorSpace << /CS21 57 0 R /CS22 62 0 R /CS23 63 0 R /CS24 64 0 R /CS25 65 0 R /CS16 57 0 R /CS17 62 0 R /CS18 63 0 R /CS19 64 0 R /CS20 65 0 R /CS12 57 0 R /CS13 62 0 R /CS14 63 0 R /CS15 64 0 R /CS8 57 0 R /CS9 62 0 R /CS10 63 0 R /CS11 64 0 R /CS4 57 0 R /CS5 62 0 R /CS6 63 0 R /CS7 64 0 R /CS0 57 0 R /CS1 62 0 R /CS2 63 0 R /CS3 64 0 R /Cs9 63 0 R >> /ExtGState << /GS28 82 0 R /GS29 88 0 R /GS30 84 0 R /GS31 83 0 R /GS32 89 0 R /GS33 90 0 R >> /Font << /T1_15 60 0 R /T1_16 58 0 R /T1_17 56 0 R >> /ProcSet [ /PDF /Text ] >> /Contents [ 67 0 R 69 0 R 71 0 R 73 0 R 75 0 R 77 0 R 79 0 R 81 0 R ] /MediaBox [ 0 0 595 794 ] /CropBox [ 0 0 595 794 ] /Rotate 0 >> endobj 55 0 obj << /Type /FontDescriptor /Ascent 764 /CapHeight 698 /Descent -238 /Flags 34 /FontBBox [ -165 -228 1000 944 ] /FontName /EDJANA+Sabon-Roman /ItalicAngle 0 /StemV 80 /XHeight 442 /CharSet (�6����7���5$�E�uG�M>�$\\wG\r;�8��R}"�E���IwWC!
