The disclosure provides methods and reagents for removing pesticides or pesticide residues from plant matter such as cannabis plant matter. The method uses adsorption on bentonite (bentonite scrubbing).

Related are a chemical warfare agent (CWA) decontaminant, a method of decontaminating a CWA using the CWA decontaminant, and a product including the CWA decontaminant. The CWA decontaminant may include a metal-organic framework (MOF) including at least one metallic compound among metal hydroxide, metal hydride, metal acetate, metal methoxide, and metal oxide, and the at least one metallic compound may be dispersed either on a surface of the MOF or in pores of the MOF, or both.

A method of adsorbing a highly reactive gas onto an adsorbent material comprising adsorbing the highly reactive gas to the adsorbent material. The absorbent material comprises at least one Lewis basic functional group, or pores of a size to hold a single molecule of the highly reactive gas, or inert moieties which are provided to the adsorbent material at the same time at the same time as the highly reactive gas, prior to adsorbing the highly reactive gas or after adsorbing the highly reactive gas, or the highly reactive gas reacts with moieties of the adsorbent material resulting in passivation of the adsorbent material. A rate of decomposition of the adsorbed highly reactive gas is lower than a rate of decomposition for the neat gas at equal volumetric loadings and equal temperatures for both the adsorbed highly reactive gas and the neat gas.

A device for separation of fluid species is disclosed. The device comprises at least one header connected to a monoblock. The header transitions one or more fluid streams between bulk flow and multi-channel flow patterns using a transition element. The header is attached to a monoblock, which conditions an untreated process fluid stream by adjusting the temperature of, and/or separating at least a portion of one or more fluid species from, the untreated process fluid stream. Fluid separation is accomplished by the use of high boiling point liquids infused into the pore structure of the monoblock with the outputs being a conditioned process fluid stream and an exhaust fluid stream. Methods of making the device and methods of using the device to separate at least a portion of fluid species from a process fluid stream are also disclosed.

A method for removing noxious, hazardous, toxic, mutagenic, and/or carcinogenic compounds and/or precursor compounds from a comingled gas, liquid, and/or solid stream is described. In one embodiment, the method is used to prepare the stream for feeding to an oxidizer, such as a thermal oxidizer, to reduce the amount of particulate matter discharged by the oxidizer and includes passing the stream through an ambient or chilled temperature condenser followed by an optional gas/solid separator, and one or more gas scrubbers prior to feeding to the oxidizer.
