Studies on the flame-retardant properties of transition metal complexes of cellulose ammonium phosphate

Durable Flame Retardant Cotton Fabric Prepared by Partial Pyrophosphorylation and Metal Complexation

“…The maximun Loi value of 28 was recorded for the pyrophosphorylatec fabric treated with Ni2+, but it was colored pale green. Thi: is in accord with foregoing reports [3,4,7,8] that th< Ni2+-complexes of orthophosphorylated substrates wen flame retardant. Pyrophosphorylated cotton fabrics treate< with Ca2+ and Mg2+, as well as those merely rinsed it running tap water, had significant amounts of Ca2+ an( Mg2+ ions.…”

The effect of acid treatment on the pyrolysis behavior of sewage sludges

“…So, it was established that small amounts of inorganic additives lead to variations in the decomposition temperatures and products obtained from pyrolysis of biomass [12][13][14][15]. In most cases, the effect of inorganic constituents on the thermal behavior of sewage sludges and other biomass samples was investigated after removal of mineral matter by acid treatment [13][14][15][16].…”

Understanding the pyrolysis of CCA-treated wood

“…During pyrolysis, phosphoric acid can change the depolymerization and dehydration mechanisms of cellulose. It has been observed [20][21][22][23][24][25] that the presence of phosphoric acid in cellulosic materials lowered decomposition temperatures, suppressed volatiles production and increased char yields.…”
