摘要:
This invention relates to a sorbtion paper which comprises a fibrous base paper material which is resiliently flexible and which is further characterized by being substantially free from loose, dusty sorbtion particles and by being substantially free of lumps and holes. Activated sorbition particles are disbursed in the fibrous paper base material, the sorbtion particles being substantially uniformly dispersed throughout all dimensions of the base material and the activated sorbtion material being present in an amount of up to about 85% based on the weight of the base paper material. The activated sorbtion particles are characterized by a size of less than about 1,000 microns and an activation rating of less than about 250%. This invention further relates to sorbtion devices for use in combination with internal combustion engines and liquid body waste devices incorporating the above-recited sorbtion paper.
