From the supplier: Ice treated with citric acid and potassium sorbate reduces bacteria counts and increases the shelf life of eviscerated fresh fish from six days to ten days. In tests conducted in Apr 1992, treated ice delayed the log growth phase and maintained lower microbial counts in Atlantic cod. North Atlantic Inc uses treated ice for packing all fish at its Portland, ME production facilities. Few plant modifications were required, and the cost of producing chemically treated ice is estimated at 1/2 cent per lb.

Description:
Sorption of Pb(II) as a toxic heavy metal ion, onto styrene-divinylbenzene co-polymer resin in the presence of ultrasound (sono-sorption) and in its absence (classical method) is presented in this work. Batch experiments were conducted to study the effect of the main parameters such as the amount of sorbent, concentration of sorbate, contact time, intensity of ultrasound and temperature on this sorption process. The equilibrium between liquid and solid phase was described by Langmuir model better than the Freundlich model. The time to reach equilibrium especially in the presence of ultrasound was very fast. This indicates that the resin mentioned has a high potential for the sorption of this pollutant ion. The isotherm constants were obtained under several different conditions. These constants were used in the calculation of the thermodynamic parameters of sorption. According to the results, the kinetics of sorption was in agreement with both pseudo-first-order and first-order reversible models. .
