A polymer {made|produced|created} from sulfur and limonene was {used|utilized|employed|utilised|applied|made use of} to coat silica gel {and then|and after that|after which|then} evaluated as a mercury sorbent. A kinetic model of mercury uptake was established {for a|to get a|for any} {range of|selection of|array of} pH values and concentrations of sodium chloride. Mercury uptake was {generally|usually|typically|normally|commonly|frequently} {rapid|fast|speedy} from pH = {3|three} to pH = 11. At neutral pH, the sorbent (500 mg {with a|having a|using a} {10|ten}:1 ratio of silica to polymer) could {remove|eliminate|get rid of|take away} 90% of mercury {within|inside} {one|1|a single|one particular} minute from a {100|one hundred} mL {solution|answer|remedy|resolution|option} {5|five} ppm in HgCl2 and 99% {over|more than} {5|five} minutes. It was {found|discovered|identified|located} that sodium chloride, at concentrations comparable to seawater, {dramatically|significantly|drastically|substantially|considerably} {reduced|decreased|lowered} mercury uptake {rates|prices} and capacity. It was also {found|discovered|identified|located} that the spent sorbent was {stable|steady} in acidic and neutral media, but degraded at pH 11 which led to mercury leaching.
