According to the Leaflet API doc http://leafletjs.com/reference.html#map-removelayer, removeLayer takes an ILayer parameter: removeLayer( layer ) but you're passing it a String: $(this).attr("id")

It looks like you do have the layer object in a variable already: mapcat52. You could save the layer objects when you create them, then look them up by id to pass to removeLayer:

var layers = new Array();

// create layer
var mapcat52 = new MyCustomLayer(latlng);

// save to layers list
layers["mapcat52"] = mapcat52;
...

// remove layers
$.each(someObj.idsChecked, function(id, val) {
    // look up layer object by id
    var layerObj = layers[val];
    // remove layer
    map.removeLayer(layerObj); 
});
