| titleOfInvention | Preparation method of sulfydryl modified activated carbon for removing malodor |
| abstract | The invention provides a preparation method of sulfhydryl modified activated carbon for removing malodor, which comprises the following steps: 1) crushing the activated carbon to prepare activated carbon powder; 2) mixing p-methyl thiophenol, thiourea, formaldehyde and water, heating and stirring to prepare a sulfydryl prepolymerization modified solution; 3) carrying out modification treatment on the activated carbon powder by using the sulfydryl prepolymerization modification liquid to prepare modified activated carbon; 4) and drying the modified activated carbon, and then carrying out heat treatment to obtain the required sulfydryl modified activated carbon. The invention further provides the sulfhydryl modified activated carbon prepared by the method and application thereof. According to the preparation method of the mercapto-modified activated carbon for removing the malodors, provided by the invention, the mercapto-modified activated carbon with uniformly distributed and adjustable mercapto groups can be obtained, the malodors removing efficiency of the modified activated carbon is further enhanced, and the method is suitable for purifying malodors containing amino groups, aldehyde groups, hydroxyl groups, carboxyl groups or phenols. |
