The PROs would enter into contracts with collection agents and establish a system (financial and physical) for assuring a reliable flow of end-of-life FLs to the recycling facilities.

Assist collection agents in identifying potential destinations for the used FLs and necessary transportation requirements. 

The proposed institutional framework with its three subsystems - the PRO, the PRF, and the SI - is depicted in Fig. 3. In keeping with the principles of EPR, the institutional framework allocates financial responsibility to the producers, and physical responsibility to the range of actors including the PROs, the collection agents, recyclers, ULBs, central and state agencies, and finally the consumers. 

Automatic Continuous Air Monitoring System (ACAMS) This system can detect G agents, VX, or mustard agents at very low levels. It is an automatic gas chromatograph that first collects agent on a solid sorbent and then thermally desorbs the agents into a separation column for analysis. 

Not less complicated processes are observed in the interaction of flotation agents with finely dispersed solid particles. A special class of the so-called collecting agents is singled out which selectively adsorb on the particles flotated. Classically, three main adsorption mechanisms are pointed out here 1) the so-called physical adsorption occurring due to the opposite electrokinetic potential values of the solid particle and the nature of the surfactant ion 2) chemical adsorption occurring due to the chemical reactions of surfactant ions with the surface ions of the particles flotated 3) formation of complex compounds on the surface. 

Most common is the theory of chemisorption of collectors at the surface of solid particles. However, it is, as a rule, at the same time noted that simultaneously concurrent processes take place, which are connected both with adsorption of surfactants at 1/g interfaces and with their interaction with ions in the flotation pulp. Thus, it is shown in [66] that saturated C 2—Cj4 fatty acids are selectively chemisorbed on calcium carbonate surfaces which provides them with an effective hydrophobisation. At the same time, C5—Cg acids are adsorbed mainly at 1/g interfaces which produces a substantial influence on the stability of the flotation foams. Free and Miller [67] have thoroughly investigated the behaviour of sodium oleate in the flotation of a calcium mineral, fluorite. It has been established that calcium dioleates are formed both in the bulk and at 1/s interfaces. In this case, an effective hydrophobisation of the surface of fluorite particles takes place both due to the interaction of oleate with calcium ions on the active sites and by adsorption of calcium dioleates formed in the solution. It has been once more confirmed [68] that classical collecting agents, xanthogenates, e.g. ethyl xanthogenate, form on the... 

In the second half of the sixties, a new paradigm was formed, which says that collecting agents form complex structures on individual areas of 1/s interfaces. In this aspect, the selectivity of the surface ion-aqueous solution ion interaction was based on the ideas of the classical analytical chemistry of solutions.

Besides these reductants the components of a sample can reduce the collecting agent that could lead to a larger button than plaimed. For lead the most important of these are probably sulfur, iron, and sulfides.
