Absorbent clay

When water is absorbed, clays will often expand as the water fills the spaces between the... 

After another major explosion in 1866 which completely demolished the nitroglycerine factory, Alfred turned his attentions into the safety problems of transporting nitroglycerine. To reduce the sensitivity of nitroglycerine Alfred mixed it with an absorbent clay, Kieselguhr . This mixture became known as ghur dynamite and was patented in 1867. 

After another devastating explosion in 1866 which completely destroyed the NG factory, Alfred Nobel focused on the safe handling of NG explosives. In order to reduce the sensitivity, Nobel mixed NG (75 %) with an absorbent clay called Kie-selguhr (25 %). This mixture called Guhr Dynamite was patented in 1867. Despite... 

For example, montmorillonite (a strong water-absorbent clay) has an average pHpzc of 2.5, and for that reason the CEC is dominant at a pH > 2.5. Goethite (a-FeOOH) has a pHpzc of 6-7, and therefore it can have an AAC at pH < 6 and a CEC at pH > 7. In the case of a-AlOOH, its pHpzc is 9.1 and it displays a predominantly AAC in natural waters. Organic suspended particles (mainly humic substances) have pHpzc values in the vicinity of 3, and thus in natural waters they are negatively charged particles with a high CEC. Natural pH values are rarely above B.6. 

Liquid pesticide spills can be further contained by covering the entire spill with absorbent materials, such as spill pads, blankets or pillows, absorbent clay, vermiculite, sawdust, com cobs, expanded silica, or other acceptable material.

SPILL CLEAN-UP blot spilled powder with a absorbing clay, which may then be removed with a sweeping compound use a one-to-ten dilution of commercially available 5% hypochlorite solution to mop up contaminated areas. 

Silica gel, charcoal, and many bauxites are inert. Many absorbent clays are inert. 

Absorbent clay - This is usually calcium bentonite diat has been partially calcined at 200 to 550 C to remove interl er water and develop absorbeney.
